If you have a God-given talent in writing, which Roosh obviously has, coupled with an entertaining niche subject, then go ahead and blog -- you might even be able monetize. Ultimately, you want your writing to be an expression of yourself and of your character as a person (ie. don't ask us what the title of your blog should be). Also, even if you are an Einstein of dating, but your writing sucks it will not hurt to just keep your journals unpublished and maybe pay (maybe a good writer like Roosh) for editing help.
