You answer:

Greetings! I know this is kinda off topic nevertheless I'd figured
I'd ask. Would you be interested in trading
links or maybe guest authoring a blog post or vice-versa?
My website covers a lot of the same topics as yours and I
think we could greatly benefit from each other. If
you are interested feel free to send me an e-mail.

I look forward to hearing from you! Fantastic blog by the way!
