You need to boil that idea down into what you really want…
Most any WordPress based site with most any theme will be fine for aggregating and curating content.
I build focused blogs that also aggregate from other sites via that other site’s RSS output, maybe a little use of Press This, the Indie Web ‘Press This’ extensions, and the Press Forward Plugin and Extensions.

You could even add a Forum to that with Buddy Press as a new social network and/or BBPress as just a forum.

Depending on your ad methods you might want the Revive Ad Server.added to your website.

You should be able to start up with both your WordPress and your Revive on the same host by using subdirectories to hold each and then run the WordPress from the subdirectory using this method.

Some background…
A few years back I came over to WordPress from the Pligg Bookmarking CMS. During my search for a new CMS I stumbled on Diaspora and the IndieWeb so I started looking at the Indieweb and wishing WordPress could be attached to the Diaspora network.
My vision became a user with a local box with WordPress on it which then settled into the Indieweb networking and either became an adjunct to a public system or became publicly available itself.
Bookmarking and content aggregation within Niche Markets and portals to the IndieWeb are my main focus with an emphasis on Multisite!
