Lately, I’ve been trying to come up with solutions to better track the numerous comments I leave both at this site and across the Internet. At the moment there still aren’t any good solutions for this problem as a whole, but services like BackType are starting to fill the void.
BackType scrapes comments off of a number of popular websites and then lets you find your comments by linking your account to the URL you use to identify yourself at those sites. For example, I commonly use the URL for this site when making comments at other sites. So BackType lets me associate comments with that URL to my BackType account.
It’s not perfect — it seems to have a fairly small coverage limited to a small number of very popular blogs. Even then, the comments it has scraped are very recent . . . for example, it only picked up 17 of the comments I’ve left at Unpublished.net.
But, it is better than nothing, and in conjunction with similar tools out there, at least gets the ball rolling to start tracking your comments.
