I've recently started swapping on swap-bot and I love it! My latest swap is hosted by kiwivandal, and this post is about it:
We have 5 assigned partners, and we have to follow them and write a comment on the post with the title: "Kiwi's Blogger Follower Swap - this way your partners know you were there and that you have hit the follow button."
What a great way to get some exposure for your blog and meet new bloggers. Can't wait to get started! You can check it out here!
