I updated to the latest Amazon SimpleDB Perl library to play with the new SELECT feature they added. I found that the lib did not work. I got pretty pissed off, because Amazon is a major company and their cloud database offering needs to 'just work' if they're going to get my business. So I mouthed off about 'SimpleDB sucks' on twitter. A manager at Amazon saw my twitter, and the next day I had email asking me about the problem. I provided them with the offending line number, and my temporary hack to make it work. They patched the software and re-released that day. Stuff like this is why I love FOSS. If there are bugs, I can fix them if I have to. Combined with good support, I get to help the owner of the code fix flaws very rapidly. Try that with SQL Server Now, that being said... there is no way Microsoft would ever have had such a fundamental bug in a library. But rapid iteration in public beta is the reason Amazon is so far ahead of MS in the cloud, so I cut them some slack... as long as they have such kick ass customer service. And they do.
