I just found out that there is a way to grab an rss feed of the themes page, get updated as to when a new one is available. That lead me to try hacking the drupal taxonomy url to uncover other things that may be available that I didn't know about. Something having it's own URL/RSS feed may be invaluable to others so i'm posting the following list here:

Compilating some terms in one RSS feed.
Also remember new taxonomy syntax for compilation some terms in one feed:
For including in the feed any message from all selected terms:
http://drupal.org/taxonomy/term/14+15+21/
For including in the feed only messages, placed in _all_ selected terms, use:
http://drupal.org/taxonomy/term/14,21/
(But really, I cannot find here any message, placed in more than one term.) :)
RSS feed link placed as usually - at the bottom of this pages, under "XML" button.
