Should I keep a seperate blog?

Been debating with myself over this for quite a while now and I still don't have an answer. On one hand I think I should keep all my gaming/pc related stuff on here and everything else on a seperate blog. But on the other hand I'm thinking, why bother, I'll probably have more luck getting readers if I just post everything on here. On the ooother hand, however, maybe if I actually added the link to my blog to my profile or something, people would go check it out... Then again, I have some serious doubts if anything I write is even remotely interesting enough for anyone to even wanna read.

So yea.. Not sure what to do. Heh. Any advice would be helpful.
