during the last year I was using GoogleSites and MS Office live to host my site. I was spending lot of time just to implement things like RSS or enable users to comments on articles I am posting there. I trust MS and Google so I thought they are providing a good tool and will not find a better ready product at low cost.
after couple of days trying WordPress (free product), I found I was making a huge mistake by hosting my site on MS Office Live or Google sites. with couple of clicks I am doing things I was spending days to implement similar functionality at MS office and google sites.
I would strongly encourage you to try WordPress as platform to host your blog and I am pretty sure you will never say “I was mistaken by using WordPress”
