Add Pingback and "other social tracking widget" under Social Tracking

Right now this section lists three specific modules and is missing Pingback.

I suggest adding a fourth line, something on the lines of "Add other social sharing widget, such as the AddToAny or ShareAll [or Digg This] modules, to help visitors post your links to social networking services." Because really what matters is that they install something (that works), not the specific sharing widget they use. (Aside from Service Links, most of the available sharing widgets seem pretty similar -- almost a seen-one-seen-em-all thing. If I were doing it, I'd get rid of the Digg This entry, but keep the entry for the Service Links module as it's more than just a third-party widget.)

Also, suggest either adding a line for Pingback or amending the Trackback line to say 'or Pingback'.
