Coming from SQL Server, I got very frustrated by the Oracle community when trying to start administering one of those databases.  I couldn't understand why their community was so much less helpful than the SQL Server community.  Very annoying to get a response to a specific question that just says "Did you read the documentation?" with a link to an 80 page document - especially when most of the documentation is written for Linux and I was managing a database in Windows.
With all the great resources for SQL Server out there, it is a great time to be a SQL Server DBA.
