Squidoo.com- Notice that there is both a fb share and friend.
V7N.com/ forum - Notice that their share list is kept to a small list. The obscure ones are left hidden behind the More button. This way, real users, can find the icons they want without getting discouraged.
T4L Plan - The top level list is good. Arguably, it should also have FB-like but maybe that would interrupt the flow of someone across the site. The More (plus) button takes users to an unrefined list which needs to be refined. The next step in design is to review what it tweets or shares as a message. Is it the same for every page? Does it take the page title? How does it work?
