I just came across this site:
English ver:
http://comic-walker.com/news/detail/58/
Japanese ver:
http://comic-walker.com/

I haven't dug into it at all yet, but it looks like it might be a decent source for some reading material. The English language title selection is pretty small, but they look like they'll be adding to it. Anyone using it yet?

It looks pretty cool, so far; unfortunately, it's only a few days old, so I don't know how everything is going to work. The company is pretty old, so I'm not worried about it going under, just what it's going to be like.

Of course, what is immediately clear is that most of these manga will require some back reading before you can continue reading it off of the site.

Overall though, it's pretty nice, so far; the reader could use a zoom button, but is otherwise much easier to use than most official web readers: you only need to click to turn the page and it displays in a tab, instead of in a separate window. They seem to have taken some tips from the scanlation readers, in that regard.

I'm currently messing around with my account to see what's there; it seems to mainly be for keeping up with what you've read, but even if that's it, it'll be pretty useful.
Registration is easy and free, by the way; only requires an email and password.

Thanks for sharing this, I expect I'll enjoy it quite a bit!
