Do you know of any good alternatives to geoserver if i have a PostGIS db with some feature gis data and i need to expose it to other people through a Web Feature Service?
Geoserver does fill a pretty big hole in the capabilities space -- it's pretty easy to get going with a bunch of layers and style them, but ultimately they're implementing a RDBMS in xml files, and it's a big, complicated, java system that's been one of the more troublesome portions of the stack (IME).
