Finding a blog subject in the era of direct social networking

I used to use this blog to share jokes, pictures I like, and interesting websites, as well as letting off steam.  Now, with Facebook (and potentially with Google+) I can 'talk' directly with people who are more likely to reply.  That kind of communication is more satisfying than random blogging.  Now I find blogging more suited to sharing impersonal information, which is at odds with my blog's name as those are things I'm seldom "happy" about.

I don't want to turn off my blog, but I'm having difficulty finding a use for it that is compatible with why I started it.

I could use it to give Snopes one more link.  (today's 'new knowledge' is how egg whites aren't miracle cures for burns)

Or I could use it for social awareness articles.  (unsafe abortions are on the rise because of cuts in funding for contraceptives)

Those uses make it a kind of inefficient Twitter.

Or I could put up more pictures.  I like that use.
