If you want to blog, blog. If people like it, they'll read it; if not, they won't.
Not sure where you're going with "do you think this is a good approach?" unless you're trying to advertise.
Also, you seem to have posted the exact same thing yesterday:

...and you've been posting links to your blog for weeks now. One mention of your blog is quite enough, thank you. If you add some interesting content that people find useful, your readership will improve.
