Oh how self-important is this? A page on how to contact me - whatever next, a bio?!?
Actually, it isn't that bad. Think of this as a polite request, if you will; especially if you'd actually like a reply.
e-mail. Use e-mail.
That's it. Please don't use Facebook, Google+, Twitter, any of the IM systems (Google Talk, et al), or anything else like that; use e-mail. It works.
You've got an e-mail address for me - use it. This way everything comes into one place, is something I can easily sort and manage, and you have a far greater chance of actually getting me to read things and, crucially, reply.
