I see a lot of anti-conference comments here on HN, and I don't get it. Every week I've spent at a conference has been highly illuminating and motivating, and recharged my fascination. This is all followed by presentations to the larger team of what I learned so that the benefits of the experience were broadly dispersed.
3-5 days in a new city seems like a huge win with the professional benefits. What am I missing?
I think that's the key. Conferences are only fun if you can actually have a meaningful connection with the people, if they are genuine peers with similar interests instead of just a bunch of people there for their own self-aggrandizement, sneaking around the corners trying to catch someone saying "dongle". Or the ones mainly frequented by socially inept nerds, like Fosdem.
So conferences can often be pretty hit-and-miss.
I'm the tech presence at many of my companies industry conferences. The city the conference is in makes no difference because I'm there to meet people and schedule accordingly. Current customers, potential customers, tech people from partners and even competitors are all very valuable interactions.
For me, conferences have turned into a cost effective place to meet in person all of the people I deal with remotely.
