If you want to build a successful blog, in terms of traffic, you will need to leave comments on other blogs. I have tried very hard to be more proficient in this area, but at the end of the day, I find myself more of a passive reader than an active participant.
One thing that worries me about leaving comments is the potential for something you say to come back and bite you in the ass down the road.
A useful tool I recently came across is BackType, a Website that lets you view all of the comments you’ve left (if you linked to your URL) on other blogs on a single page.
You can also display all of your comments on a widget that can be placed on any blog or Website.
The site also serves a purpose for those of you that read blogs but don’t write them. BackType hopes you will set up a profile page with them, and use that URL behind all of your comments.
Another use for the site is to monitor if anyone is using your URL in vain, putting it behind comments that are impostors or just plain spammy.
Just like Twitter, you can choose to follow folks as well.
