Out of the several hundred persons who saw my two talks during the #FOSDEM weekend. One(!) has provided feedback using the site. On the bad mike/speaker setup.

My point is mostly to fellow speakers: don't assume people will use that system to say anything. Good or bad.,

I had maybe 20 people tell me to my face they liked one or both of my talks. A better feedback channel!

@bagder I've been visiting fosdem since... *checks tshirt*, 2015, and I've honestly never noticed the button, I had to CTRL+F to even see it...
But on the other hand, I'm happy enough knowing that most people just find it hard to show appreciation, and just silently enjoy it.
@mid_kid I've been to FOSDEM since 2010, I don't think I have ever submitted feedback on their site for any talk...

@bagder I always thought I was 'late' in joining the RB/cURL gang going to Fosdem in 2010... it was first time for everybody then?!

Still need to check if I bought a t-shirt then (for next year)

@peturdainn yes, it was the first time "us Swedes" went there at least. I know Frank went to at least some earlier ones.
@peturdainn @bagder My first FOSDEM was 2002, although I did also go to OSDEM in 2001 :)
Went fosdem t-shirt hunting here at home and found the 2012 one which I think is the first one I bought.
