^ yup, may mga automation tools sis, on many webhosts, but that's not enough. they are mostly useful lang sa initial stages - in setting up your blog. but not anymore if you need to maintain, fix (a hacked blog) or even modify your installation - and in this case you'd need a techy friend to help you out (maybe you could barter skills? doing maintenance is not all that easy in many cases especially if you want a hacked blog fixed) or just simply pay someone to fix things for you.
mas magastos talaga ang may sariling WP, but it could be worth it especially if you are earning something from that site.
