Blogging bungle or bonus?

For some reason I have been wondering lately whether to move to wordpress or better still, to get my own domain name. I have been playing around with WP and I'm not too happy that you can't change fonts or the themes like you can in blogger. Hence the 'own domain name' bit. I thought at first I could get some satisfaction changing my blogger template...but I haven't found any that are well suited. 

The reasons I also don't want to change include that I have promoted this blog big time and do have good readers/followers. I'll lose my google page rank and other promotional stuff if I change my platform. I'll have to start from scratch. I wonder if I host my own domain name using my blogger profile will result in me being able to maintain all of the above. Or maybe not.

So anyone with any ideas?

It's not good when you are technologically challenged like me and want to do stuff with technology!

Until next time,

Cheers!!!
