Of course sharing this tidbit is going to make me that guy*, but if the word "meme" to you means "a picture with text written on it" then chances are you owe at least some thanks to the Cheezburger Network. This site (and later, series of sites)has been built around the business of collecting viral internet images for the lulz. Now, several realms from this digital domain—including but not limited to Memebase, FAILblog, and ROFLRazzi and a couple dozen others—are available via the new Cheezburger mobile app.
Amuse has been out for some time now, and there certainly are apps like it, but we decided this one was worth mentioning simply because it works great and has an insanely high rating on the Android Market. The function of this app is very simple, it basically provides you with a mobile feed consisting of the most popular 'entertainment' sites like Rage Comics, Demotivators, 9gag, and many more. Populate the app's home screen with your favorite sites from the list, and see a feed of content directly from the site in an easy-to-consume mobile layout.
