Kunal’s thoughts on qualifying tweets outside your normal “realm” with “off topic” (the bookmarked tweet being an example). Don’t think it’s necessary at all, but also understand why people do it. If you know/believe that people are following you for a specific reason, then understandable [to] qualify it. Some people use Twitter to exist as full people—all things they are interested in and care about are fair game. Others are much more focused on a specific passion or something that aligns with their career. FWIW, I prefer the former kind of person in almost every case. The same drumbeat gets boring after a while.
