I decided to start blogging about MySQL stuff in the different blog http://www.mysqlperformanceblog.com
For LiveJournal users - I've created syndication account "mysqlperf" which syndicates my new blog, so you can just add it to your friends list if you want to follow new blog.
PlanetMySQL.org is not updated yet to include new blog. I hope this will happen soon.
Lets hope I'll have time to update my new blog more frequently. And your comments surely would be good motivator :)
