http://unused-css.com/ Does some of what you ask, and they have this to say:-
Latish Sehgal has written a windows application to find and remove unused CSS classes. I haven't tested it but from the description, you have to provide the path of your html files and one CSS file. The program will then list the unused CSS selectors. From the screenshot, it looks ...
Assuming you don't want to use a specific Classified Ads Content Management System, I think that at this point you should consider Drupal as well. Drupal is very effective on user/permission management by default, and Drupal 7 already allows custom content types by default.

Almost any CMS you choose answers those requirements (save for the syntax highlighting when typing, that I've never seen unless in ace or cloud9).
You could close your eyes and just randomly pick one.
Here are my personal recommendations:
If you want something set up in less than an hour, I'd recommend wordpress with crayon syntax highlighter. In wordpress, ...

It seems that I'm able to answer my own question while using the new Custom Search API.
Creating a Custom Search Engine will initially ask you to provide sites or pages that you want your CSE to search in. By filling in a sample website and creating the CSE you are then able to manage and adjust it after the creation process. Here you can tell the CSE that ...
With a bit of more creative searching I've found Rateback, a free service from Citricle. Powerreviews also has its own Customer Reviews service, although it's not free and more focused as a service for large enterprises.
Lastly I've also stumbled upon an opensource review script that can be used to set up a complete reviewing site.

Use a XMPP server like Openfire to handle the chat sessions. Then you can write your own XMPP client (e.g. in jQuery or wherever you want to run the client on) or check out this nice thread with several web-based XMPP clients.
There are some pretty nice options available to you when it comes to Open Source, I've listed the best 3 that I'm aware of below for you:
OSQA is an open source Q&A platform similar to StackExchange, definitely worth looking at if you're considering open source.

They've basically made a mashup using the APIs of these various apps and services. You can "get" exactly that by signing up for their service.

The SPIP content management system can do what you want, and it's free in al senses.
It has some extra interesting features for collaborative editing: a general private editors forum, private and public forums for each article/page, calendar and an internal messaging system. It's extendible with dozens of plugins and can be easily installed by anyone with ...

And they're all capable of being used to write specific features like ratings, comments, tagging, etc. The more popular a framework is, the more plugins it might ...
