And you know this isn’t even the tip of the iceberg. There are plenty of other sites for SQL Server, Excel, Biztalk, non-English sites, etc...that aren’t listed; as well as a very large pool of non-Microsoft bloggers. Someone said to me the other day that ASP.NET didn’t have as many online resources as PHP. Well, I don’t know if this is true but I am pretty sure that if it is true...it really doesn’t matter. There is too much and then there is too much. There is plenty of information for both technology choices, so that the decision between one or the other should be based on business needs and developer experience.
