Good post.
I'm familiar with many of those "techniques" because they're very common on writing sites and forums as well (e.g. AW, Authonomy... not necessarily bad sites, but with a lot of bs from people just trying to promote themselves).
Good thing is, though, after a few years of practically living on sites like this and blogging, I've learned it's pretty easy to spot insincerity. Most of these people aren't as good at pimping their blogs as they think they are.
The way I see it is I will get out of blogging what I put into it, and so the best thing I can do is be sincere with my own actions.
