The idea of trackbacks and pingbacks are great. It’s a way of getting notified when someone else posts about you on their blog. However, spammers have taken over and it makes you wonder if there is any value in trackbacks anymore.
My guess is that most bloggers will say that the value is little to none. The number of spammy trackbacks are overwhelming at times and, even if you do have a good spam plugin protecting you, the ones that get through are not quality. The chances that a good trackback comes into your site is rare, but when it does, it is great to see.
