No links to back out of blogs/blog comment view

enter blogs via header button = get listing of titles & brief view of content

click on chosen blog = page displays, but no links back up a level.  Requires back button use or reload from "Blogs" button (what if I don't want to start from scratch???)

click comments for chosen blog = comments display, but no link back to same person's blog entries and no link back up to more generalized blog listing I started from.   Requires back button twice, or restart from "Blogs" button (ref. earlier comment on starting from scratch)

I like the forum format where there's a set of links that can take you back to any of the prior levels above where you are at that time.  Easier and faster to navigate around that way.
