New blogpost:

@neil also my first; agreed on many counts. It some rooms it felt like the heating was set super high where none was needed

@annehargreaves I guess that it must suit some people, as it has been running a long time, and I am just a first time attendee!

@neil it was lovely to finally meet you in person. I was entertained by your apparent fan club too!

@Synchro Yes, a pleasure to finally meet you away from keyboard!

@neil Your experience aligns with mine from more than 10 years ago. The absolute crush of people was overwhelming, for me. Some of my colleagues at the time were totally into it and energised. I never went back, despite feeling it was and still is very relevant to my interests.

@anticdent Yes, it clearly works for some people!

@neil these are all the same reasons that I don’t go to fosdem anymore. Once I realised I was spending more time exploring Brussels than trying to get into a room that had people camped out on all the seats since 9am I realised it was time to stop going. I’m happy people enjoy it but it’s not for me

@neil I feel the same way, which is why I've never been to Fosdem (I like the idea, but there are far too many people, I prefer max 150 as it feels more like a community and I can talk to everyone if I want to). A good example of 'victim of its own success'.

@neil that was an interesting write up. My plans to attend have been thwarted for two years running. But perhaps that was for the best, I do not cope well with crowded places, that's why I rarely visit London. ( or even my nearest city Nottingham for that matter).
Thank you for sharing your thoughts.

@neil

Thank you for sharing. Your post was a good reminder to me that its ok and normal to have those types of feelings about events, and I dont have to follow the expected social script.

@neil

Pro tip: Sundays were great though as many people hungover staying in their hotel room maybe the new generation drinks less and that's not the case anymore

@neil
I went to Fosdem many times. First time was in 2001 (I was still in engineering school back then). We had some crazy coding geek camp at nights (in our hotel room)

It is great to see how popular this is but the last time I was there it was clear that this has outgrown the place.

Long story short I would not go back today. I watch a few bits on the recording instead. I am not involved in the OS community to make it worthwhile. Probably also a bit too old (mid 40s)?

@neil I had pretty much the same experience last year. I don't want to go back.

And as for watching the streams, there are often problems. Just earlier today, for instance, all audio stopped working. Of course, since there's no A/V people in the devrooms, no one told the presenters. A cooperation with https://media.ccc.de/ perhaps?

My experience last year:

@neil fwiw it’s generally quieter on Sunday. Especially in the morning. Good time for stalls

@andre Thanks!

@mc Oh, interesting - that's a shame about the live stream, but I guess that that is just a side effect of volunteers doing their best.

@jmtd I decided to head there anyway, so I will see what it is like in a few minutes!

Thanks for your honesty Neil. I too am not keen on large crowded spaces especially although I do feel that one day I'd have to visit one of these conferences to get the experience and meet folk that maybe I follow or follow myself here. The term I use is "This place is too peopley". A totally made up word but I think it'd be one you use too?

@justine

I was definitely peopled out by the end of yesterday.

And yet the people were also the best bit...

@neil

I haven’t been to FOSDEM for ages, so some of this may have changed:

The first year I went, there were about 3,000 people. It felt enormous. The beer event on the Friday was packed, but we did get a table after about an hour (and then stayed until 6:30am). A lot of people who had used code found me (and bought me beer, which contributed to the late night). I went to some talks, but mostly it was an event to chat to people. The talks I went to were interesting but were mostly they were useful because each talk would be attended by 20-50 people who were interested in the topic and talking to them was useful. Often they didn’t actually attend the talk: arriving a bit late and not being able to get into the room would leave you surrounded by half a dozen or so people who were also working on the thing the talk was about, going to have coffee with those people was often more interesting than the talk (talks are less interactive and you can always see the recordings later).

I gave a in track talks a few times (at least two, possibly three? I lose track). This is definitely worth doing because of the breakfasts. Main track speakers are put up in the Novotel on the Grand Place and so they all go to the same breakfast. I had breakfast with Chris Lattner one year. With Simon Cozens (who had just given a talk about his new typesetter, SILE, a project I would have created if I’d had time and was super happy to see someone else doing) another.

The busiest year, I gave four talks (one main track, three dev room). This was the first year they expanded to the buildings that were a bit further away, and also the year it snowed and the temperature dropped to minus ten. It took several years for the skin in my nose to recover from waiting half an hour in that temperature for a taxi. Walking over the ice between the rooms was difficult. Not my favourite year, for several reasons.

The dev rooms are not really organised centrally in any meaningful way. It’s better to think of FOSDEM as a set of colocated federated conferences than one big one. Some dev rooms focus entirely on talks, some use it as more of a hackathon, a lot are somewhere in the middle. There’s no coordination of schedules because they’re really independent events that happen to be next to each other. You can walk between them easily, which is nice if you want to got to more than one, but you often get the most value by spending half a day or a day in a single dev room, especially one that isn’t back-to-back talks.

After the first couple of years, I mostly skipped dev room talks. I went to a few of the main track ones, but spent most of the time focused on talking to the other attendees.
