This is a very good question, as the way we formulate and type our sentences tells a lot about ourselves. I think my posts lean towards cheer and friendliness, but sometimes I feel the need to be a little... caustic? So I try to shape the tone into something that would be suitable in a banter, something that people can enjoy despite the slightly acidic spurts; compare it to lemonade for instance. Overall I'm content with the way I display myself here, though in the first half of this year I took the whole caustic thing a little too far as I wasn't in a very good place to start with--hopefully this counts as an exception.
