You know, building links via forum and blogs comments used to be a very effective SEO technique. However, the world of SEO has changed a lot, and now this technique doesn't work as it used to (and potentially can be harmful, if you leave tons of irrelevant spammy comment with your links).
But it doesn't mean that you shouldn't use a link to your site in your signature on forums or mention it somewhere in blog comments.
Search engines, in fact, read those links and take them into account. Even despite the fact that most of blogs/forums are NoFollow these days (which at least in theory means that they carry no link value) you can benefit from them!
These links will be used as a meas of building relationships. Every time you leave a comment, a blog owner or a forum visitor takes notice of you. This is especially true for repeat visitors, so it is worth returning to the same blogs/forums over and over. If you write really worthy relevant comments, people will definitely visit your website and perhaps (if they like it) they put a link to it.
So I would say that forum/blog commenting is an effective means of attracting good quality links to your website and help with your overall SEO efforts.
