Instead of Tweets, Counter Social uses a euphemism for passing gas.

So I signed myself up. It is free and thus far (2 hours in) it has been good fun. You can see my profile here. I have not a clue how big the community is, but engagement has been fantastic. I Tooted (the equivalent to a Tweet) 4 times (one intro & three replies) and already have six followers. 600% in 2 hours, yay!!. I made my profile public.
