[Gentoo] One blogging app, please?

I was thinking about how I have three different programs open right now related to blogging. I’ve got blam to aggregate stuff for reading; then I have to open all these blogs in Firefox to either see the rest of the post (because the RSS doesn’t have the whole thing) or to respond in its comments area; finally, I often write responses in my own blog using LogJam.

Does it seem odd to anyone else that all this functionality hasn’t been integrated into one all-encompassing blogging app? It would be like the e-mail client of the blogging world.

Or perhaps this has already been done. If so, please let me know.
