Well why not have a contest and give away a few magnets or pins with your Blogs logo on them. Like this company for instance:
Here is their company Logo and then here it is on a glass tile magnet or pin. This one is a magnet.
Here is another one. I just chose one that was on my blog. This is Graces blog button .
If you are interested in having some cool give aways just contact me at email@example.com and we can talk about it.
