Help needed: Everything Or Separated ?

And again, I feel I need to do something about this site.
First of all, I ask myself, is it convienient for you if I write everything here? This is mainly for longer articles for Twitter, Buzz and other social sites. But on the other hand, there are a lot of different topics, so it might be hard for anyone to subcribe to the feed, because everyone seems to get annoyed with topics they don't care, so everyone is unsatisfied.
Now I'm thinkin g to use this only for very private posts, like this one, and make separate blogs for the Topics Android, Geocaching, WebM and Anime (oh yeah again :) ). In addition this will be the portal with Twitter & Buzz-Feed, and a list of links to my other blogs.

What do you think?

Update: I already made a decision. I split the topics. But still I would like to know, what you're thinking. Is it better or worse ?
