Josh,
In terms of people who want to attend both, but need to ask their boss's
permission, I think there *is* a difference between "2 weeks" vs. "over
a month". The likelihood that any boss would pay for his staff member
to go to two different PostgreSQL conferences in the same month is very
low. If, however, the two conferences are more than a month apart, in
different quarters, it's an easier sell.
And while the attendees who do both are not the majority, they are a
significant number and are probably dedicated community members, so we
ought to at least think of them.
Also, I agree with Robert that it would improve both conferences if we
could swap the dates of West and East, because:
-- even less "ask the boss" issues for East Coasters
-- Speakers who do both would be able to develop more different content
for both conferences
-- Having a conference in the East every 6 months, instead of two in 2
months and then nothing for 10 months, would help keep interest in PG up
year-round in the Eastern US
-- You might attend pgCon, learn from how Dan runs his conferences,
solicit for pg.US and the next East (I can dream, can't I?)
