There's a software app out there that searches for potential urls that might be worthwhile to approach for linking. I have not used it, but I saw it on the web. Until now, I've been doing this manually. I don't think this does more than search for potential contacts (and it seems to prepare a letter which I'm disinclined to use). But, this endeavor being what it is, I'd like to ask about it before using something like it since there are so many flags up. I might inadvertently be doing something that is not a good idea.
So I'm asking for opinions/advice!
