. . .trying to 'my-space' this place won't work and isn't what the website is about in the first place. . .

Though not as imperative as some of the other items on this list (hence the 4 stars), a last activity date is relatively common on other websites (so it can't be that difficult to add). Not only would this feature be informative for the mere inquisitive, this feature would have practical effects as well. One that immediately comes to mind is determining if a member is still active prior to sending an item suggestion for a weblist. Moreover, a weblist created by an inactive member may need to be replaced by a list managed by an active member. One could argue that the last comment date provides this info, but members don't also post reviews.
