In a similar vein, for those who have worked with MySQL, how different is it from other SQL databases? I have a lot of experience with a variety of SQL databases (SQL Server, Access, Informix, DB2, Oracle, and a couple of obscure critters), and am wondering if I actually need to pick up a book and do some studying before I start working with MySQL or if a little bit of playing around and using Google will be sufficient.
Also, anyone played around with RSS? I'm starting to think about messing around with that as well, and am not really sure where to start.
Many thanks for any light that can be shed or help that can be given.
