blogs about "a better way" to meet people at Linux conferences.
He suggest people should buy speakers dinner ;)
Actually I can't remember the day we started doing this.. it must have been ages ago.
And I also don't even remember which developers I bought dinner already ..
(I`m not even gonna try listing at which conferences I paid the bills)
But .. is that so unusual ? I have a couple of collegues that also just do this.. they go out after a conference and buy the core members of their favourite project some drinks or food, just because they appreciate what others are doing.
