Want to stay in the know about Windows Server and related topics? Social media is one way to do it. You can find any number of self-styled "experts" on tons of topics on Twitter, but not all of them are worth following. Here are the accounts that provide the biggest signal-to-noise ratio (not including @WindowsTT, which of course you already follow).
Note that this is not meant to be a comprehensive list of experts, but rather a collection of people (read: not robots) who specifically provide value on Twitter. Got someone to add? Let us know. You can follow all these experts at once through our Windows Server experts list.
