stop making tor happen
Hosting on a private PC isn't really that an option. It's okay for small personal sites, but for sites, that will attrackt many users, your upstream probably won't hold the load
(and your ping is shitty

)
And depending where your home is, you'll get other problems ... like your ISP blocking your Internet, because it gets DMCA
Since you don't want to hide it on tor, to attract more users

How much space and bandwidth do you need?
and do you mind paying a bit per month? If not, i could ask a few people, if they can do a blog-hosting for you.
But keep in mind that offshore, DMCA ignored webspace isn't as cheap as some legal company. (depending on your needs)
You can use
e.g.
http://en.wikipedia.org/wiki/Serendipity_(software) or
http://en.wikipedia.org/wiki/B2evolution
which are small and not that complicated (i think), though not as mighty as wordpress.
Wordpress is actually the best thing you can do.
As for the consequences of using such a service:
Probably non, if you don't use lolicon. if you use... don't really know. if you aren't from USA, probably not that much. but who knows
