Strongly agreed. If you do not intend to put a stored procedure in the master database (which should not be done unless you have a good reason for doing so and know the consequences) then do not use the "sp_" prefix. On the rare occasion when you want to place a stored procedure in the master database (usually your home-grown administrative procedures) then you can use "sp__" with two underscores to avoid colliding with current or future Microsoft stored procedures.
