Does your company do Python and PostgreSQL or PostGIS? Do you want to make a good impression on the PostgreSQL community? Were you planning on attending PyCon anyway?
If so, you may want to sponsor our first-every PyPgDay on March 13th. Sponsorships are due by February 28th. We expect 90 to 140 attendees at this event, so it's decent publicity for a low, low price. Net proceeds go to benefit the PostgreSQL community via PostgreSQL.US and the SFPUG Meetings Fund.
More information on the PyPgDay Wiki Page.
Of course, we want you to speak too! Talk proposals are due by January 20th.
