Following:

This tab displays all the pages (articles plus other stuff) that you are following on the current wiki (i.e. the wiki you are on when you click this tab). Articles from other wikis are not included, I would imagine, because the backend is geared more towards individual sites rather than server farms. Of course, Wikia could modify this feature to show what you are following across all wikis, but some users would probably find that more trouble than it is worth. The reason is that some users contribute to 5+ wikis have have been for a long time (2+ years). Can you imagine how long the following list could get? Now imagine scrolling though that list; it would take quite a lot of time.

User Activity:

This tab is only on Community Central and its equivalent sites for other languages. The purpose is to provide a list of every wiki you have edited on. If you want to see a list of your contributions, then use the "Contributions" tab (which, like the "Following" tab, only shows activity for the current wiki).
