This week I'm finishing up some work for submission, though I'm having trouble figuring out where to send them. Both ESA and APPROX/RANDOM have deadlines on April 12. Then WADS has a deadline April 24. (Update: my bad, I misread; that's the date for when acceptance i s announced, not the deadline!!!!) Actually, it looks like WADS and APPROX/RANDOM are scheduled on the same dates, and even though APPROX/RANDOM is at Berkeley, Christos Papadimitriou and Richard Karp are apparently invited speakers at WADS, so I probably wouldn't get to see them. Arguably one of the papers is big enough it could be worth waiting for SODA, but my co-authors seem disinclined. Arguably I'd like to submit both to the same place to minimize possible travel, and this also gives the edge to APPROX/RANDOM. (Berkeley's not close to me, but my co-authors may end up going, and if I go, there's always enough things for me to do in the Bay Area that I can make the trip worthwhile.) I'm sure there are other deadlines I'm missing that someone can tell me about in the comments.
While it's nice to have lots of possibilities, somehow all this makes me feel that our community has perhaps a few too many smaller conferences and workshops. Somehow when multiple things are scheduled on the same day with some frequency in our relatively small community, it seems like we ought to consider whether this is the right setup.
