I subscribe to a lot of blogs – maybe too many! But I saw a thread the other day where someone was looking for more SQL Server Blogs. I’ve got a couple of links here that you might find useful:
All SQL Server Blogs from Microsoft: http://msdn2.microsoft.com/en-us/sqlserver/bb671054.aspx
SQL Server Manageability Blog: http://blogs.msdn.com/sqlrem/
That last one is also a list of some other usefull blogs. Check these out!
