I have a domain that used to be PR 2 and has 115 backlinks. I used to have a site for it, but now the domain doesn't point to anything because I haven't wanted to make a site with it. The domain has expired but I can renew it. Would it be better to just let it drop or could I renew it and then sell it for more because of its backlinks and former PR status?
might as well renew it if you think you will use it. You can always place a rss reader on it until you want to use it again.
I would renew it if it is a good name. If the name isn't any good for anything and you don't use it anymore, I'd let it go.
