I guess it goes without saying that "everybody" should have "their" blog in a responsive page design. Ideally the blog should also be able to have a similar appearance to other pages on one's site.

Foundation Framer comes with templates for blogs BUT they wouldn't have any "back-end" intelligence to sort the blogs using tags -- don't know, myself, how any of these things work, so excuse any dumb comments I make. Sometimes one sees free (high priority for that) blogging services fitting you into THEIR designs -- and I didn't buy BB/RCS, maybe RSD, to do that -- this would seem to be the problem with any (?) "Content Management System", but perhaps such systems have their place if one has a lot of content on their site -- on my "old" site (pre-responsive design) I've got over 60 pages, and that's only going to increase! ;-D

I'd also like to incorporate site-user participation -- using things like Disqus comments.

Anyone able to help me find my way through this, to me, highly confusing morass of options, please?
