Yes. you used to be able to click on the # of posts and it would bring up every post you ever created or replied to. On the last update, when everyone lost their blogs (which have now been restored) they also reduced the amount of activity tracking to roughly 2 months. In doing that, they eliminated the post referencing ability from below your name.
Another place that could save alot of memory is on the home page. When the number of friends grow, so does the Friends Activity list. A friend of mine, who has @ 100 friends said his list is over 700 pages long. Mines 151 pages and I only have 24 friends. Most of this info is worthless. Unless you're that interested in seeing who your friends are making friends with. Long drives and such yeah maybe. Not something that cant be found on their profiles. I guess it's a good quick reference, but could be shortened to maybe 3 days to a week at most.
Sorry for the ramble, got thoughts but cant seem to...oops...there i go again.
Happy Golfing
