With Christmas coming (WOOT!Less than a month!!) have you considered using your Christmas Gifts as a way to promote your blogs?
I leave a Christmas card with Money for my Garbage man, as well as my Mail carrier, but this year I will be including promotional pens in the envelope as well.
People, by nature are curious, and they will go to their computers and enter the URL provided on the pens, and with any luck, they will then be hooked on your site and you will have gained an extra reader!
The more loyal readers the better!
Give it some thought, but don't take too long, it takes a bit of time to get the promotional items made up and mailed to you!
