The netvibes hack to increasing your RSS subscriber count is already making the rounds of the blogosphere (net slang for the world of blogs). But what does it really achieve?
Bloggers who feel tempted to try out the hack must bear in mind, that this is like putting putting up a fake advertisement. While it may make readers want to subscribe to your blog feed to begin with. But if your blog does not have anything worth reading, it's not going to be a lot of help :-)
So stick with producing quality reading material. After all there is no "cheat" to success.
