I started to blog this past August. It is at http://jackalltrade.blogspot.com
The service is blogger.com backed or owned by Google, I believe. The blog is about all the nitty/gritty on everything anything technological. So far, sample of topics included custom transport configuration of Postfix on RHEL 4 AS (CentOS 4.3), load-balancing farm configuration using Citrix Netscaler NS7000, software RAID5 on Windows Server 2003, technical interview and job offer discussion. check it out and let me know what you think.

Your website looks pretty nice as blogs go. It is not terribly original, but it looks nice.
As far as the content being too broad, it probably is or will be. From what I've seen, many websites that try to cover too much don't make anyone happy. It is typically best to find your groove.
Good Luck to you!
