Thank you for posting a link to the Photoshop Online Resource Guide (PORG). I have been working on this for close to 5 months and will likely continue working on it for at least another year. Don't let the plainess of the site fool you. The site is designed for quick results and precise answers (hopefully).
Actually the site is far more than Google search results on 500 or more Photoshop / Photography related topics. Specific tutorials, video tutorials, actions, plugins, filters and much much more are specifically covered.
For instance, if you are trying to find out how to extract a subject or object from it's background and then replace the background with something totally different or less distracting... I have a complete page just for that here:
http://porg.4t.com/Extract.html
If on the other hand you want to know all about Actions you would go here:
http://porg.4t.com/DRActions.html (thanks to Danny Raphael for this impressive 280 page document!
If you wish to see the most recent adds to the Guide you can go here:

And of course don't forget the one bookmark you will need to find virtually anything:
http://porg.4t.com/Nav.html
Enjoy
