Great, this gives me a much more solid idea about your company :) Since I'm very affected by the email-suck problem (in this exact moment my gmail account displays 1705 new emails in inbox, I no longer press the archive button in order to optimize my time, but use it like... twitter :-\ ), I'm also very excited about what you are doing. Thanks for the reply.
1. I can't say exactly what we're doing at Xobni yet except for "We're making email suck less" :-) The work here is at the intersection of Machine Learning, NLP, systems programming, and UI stuff.
2. The salaries we offer are very competitive - more than at most competitors. We want people to be happy and not have to worry about money in SF (an expensive city).
3. San Francisco is beautiful. From the Xobni office, it's 10 meters to shopping, 2 blocks to Union Square, 4 blocks to world-class museums, 30 minutes to the ocean, and 4 hours to skiing. Hard to beat that.
We actually give people three displays (not two).
Sounds good? http://www.xobni.com/jobs.php
