I just started
http://mysql-code.com/wp/ as my own version of http://ora-code.com

Why? well simply, when my server apps send off oracle error emails to the IT guys, I automatically format it with a link to ora-code.com so that they can get some info about the error code. Politics aside, it helped the junior DBAs and IT guys to better understand the problem and fix the errors faster.
Instead of hours, it took moments because they could just click on a link and it told them everything they needed to know about the problem.

Now I have a site for my MySQL server project. Now I can send them auto-formated error emails with links to that site - and if I don't have a page set up - I'll add it.

It should be educational for me.
