I'll be going to two VERY different events this month: Linux Tag with thousands of visitors and a big openSUSE team and the Dutch HCC Linux Themadag which I expect to be slightly smaller - by a factor of 10 or so.
I'm not really sure what kind of event I like most. At LinuxTag I'll probably be more busy to talk to people who know a fair bit about Free Software, get interviewed, discuss things with other FOSS people in many one-on-one or small meetings etcetera. At HCC, well, there will be few people I know and most visitors are probably quite new to Linux. I really look forward to meeting the dutch openSUSE people (most of whom I don't know yet) and yes, I always enjoy talking to newbies. But LinuxTag has lots of friends, both from within openSUSE and from other projects - that's also awesome.
I think I'm gonna decide that they're both equally cool.
And if you live close to either, be sure to be there & say hi to me!
If you want to pick me out of the crowd, a helpful tip: my hair (both on head & chin) got a bit longer since the pic above was taken!
