Add, remove, and update entries in the "Praise for..." page

The praise for JCiP is lovely, but a lot of it seems dated. There might more recent praise that we could add, and some of the existing items might need updating (affiliations have changed) or deletion.

We use three of these items on the home page. We might want to reconsider which ones and how many should appear there.
