Most of the people I know wouldn't post anonymously so I can assume it's someone I don't know. Which leads to it possibly being a ruse, but I doubt it. Someone from customers_suck, given I mention it in that post? Maybe. Regardless, if I seem nice enough for them to read through some of my posts and comment once, there's a probability they'll return again another time. Hence adding this post now.
I always enjoy talking to new people, so if I can find who this person is I'd be interested in talking to them. Hmm, I shall ponder this further after a bath.
