As you’re probably aware, I’m enthusiastic about Twitter – not only as an active user but an interested observer of all things Twitter, which explains why I started a Twitter-focused blog, Twitterrati, last year.

One of my favorite Twitter resources is @Twitter_Tips, which generates an impressive flow of updates about interesting, valuable, cool and entertaining services, as well as news about Twitter.

I decided to see who was behind @Twitter_Tips so I sent them a DM, and before you knew it David and Sarah had agreed to a Q&A. The post, which appears on Twitterrati, pretty long but well worth the time.
