I've obviously been reading and writing far too much code recently. I find myself mentally adding markup to my normal conversations. When I say something like "Despite having a sore back, I managed to vacuum the flat.", I mentally wrap an href round "Despite having a sore back", linking it to a previous conversation (usually with someone completely different) so that the interested listener can open that conversation in a background tab and check it out later...

As long as I don't start carrying around a small yellow sign saying 'Digg this', I'll probably recover...
