Commenting on an old post

[nbeske]

I've been playing around with OSE and found one of my competitors has a decent link coming from a post created in 2008. It only has two comments, one from my competitor with a link back to his site. The page has a PA: 55, it seems like an easy link but since the post is 3 years old im not sure its appropriate even though commenting is open.

Any thoughts?

If you can add something relevant and useful to the comments, I don't think it will hurt.

I'm not above re-visiting an old blog post, but like PeterM22 said, make your comment useful and relevant.  Sure, you're kind of using the blog for a backlink, but in exchange you're giving them some content that will pull in a long-tail visitor one day.  Or at least that's how I justify it in my head.
