Please respond by saying what sorts of TTRPG things you're pretty likely to either talk about or respond to if you see them.
This can be a list of games (D&D! Tribe 8! Fate!) or categories (the weirdest of indie stuff! NSR! Anything PBtA!), topics (Worldbuilding! Publishing!), stuff you're making, meta-commentary (The State Of The Industry), and so on.
Then maybe share, and if the replies are building up, check them for new people.
