Get more visitors, and it'll probably solve itself.

We get about 40,000 visitors a month, and have only a couple hundred unique posters during the same period. Participating users are always significantly less common than lurkers.

Of course, you might have more friction preventing participation than you should. Is your signup process crappy? If you ask more than two or three questions (username, password, optional email address), then your signup process is crappy and needs to be fixed. Do you require all posts to parse a CAPTCHA? Once during signup is probably enough--it's certainly enough until you have a spam problem to deal with. Do you make people agree to a long "terms of service"? Unless you really plan to enforce it in court, don't make folks click through...just include it on the site somewhere so you can point to it when you want to revoke someone's post privileges and need a fair reason to do so.

And, maybe you are boring people to death. I don't know, and couldn't help if you were. Just keep working on improving your site, making it sticky so people stick around and tell their friends about it, provide good content so that search engines send people your way, etc.

Yeah, big spikes in traffic often equals more customers. But not always. If you screw up the demographic data in an advertising campaign you just get clicking monkeys who likes to install spyware.

People like my software, but are probably bored to tears by my web presence. And therefore I get very few comments on my blog. I was hoping for more info so I can tune my software. Maybe I have to build in some social stuff into the main website ?

Do you have forums?

A blog is just not useful to the vast majority of your users (or, even if it is, they are not investing the time to read it). Our product website gets, as I mentioned, 40k visitors per month...our blog gets about 2000. Our forums are very active, because they provide a mechanism for people to get help and talk about their problems and goals. People love to talk...but it sounds like you're wanting them to only talk to you (because commenting on a blog feels like talking to one person--talking to a forum feels like talking to the world), when what they really want is a range of experiences.
