Harker now has his own Twitter account, in which he'll be making grumpy tweets on a daily basis. Please feel very free to add him, and feel equally free to annoy him as you please. Expect random abuse and thinly veiled accusations if you attempt to engage him in conversation, enjoy him, and please tell your friends. Retweeting of his more outrageous statements very much encouraged!
Yes, it's sneaky viral marketing of the Harker comic - but I think it might also be lots of fun ;)
You'll find him here: http://twitter.com/DCIharker
