Will having my software in low quality directories hurt my ranking?

Matt's answer:

CUTTS: Richard M from Australia asks, “We saw a software product and there are hundreds of software download directories on the web of varying quality. Could submitting our product to all of them hurt our rankings or domain trust or authority?” Okay, so we’re talking only about a software product, a dot exe, not about a website. If it’s only a software product, then I wouldn’t really worry about it. You know, some of those directories are not high quality and we might end up taking out or scoring differently those directories, but it wouldn’t hurt your website to have a link from those software directories. Now, website-wise, you know, I would definitely recommend not submitting your site to hundreds of directories. But you’re talking about a software product, so if that’s what you’re confining your self to, then I think it doesn’t hurt to go ahead and have your product listed in all those software directories. You know, if any of them are low quality then we try not to score them highly or we try not to keep them that high in our ranking or how we crawl the web. But it doesn’t hurt to have your software listed in that directory.
