Appolicious, the website known for its mobile application recommendations, has today launched a revamped Android-focused offering at AndroidApps.com, complete with an accompanying mobile application.

The Yahoo partner, which originally debuted back in fall of 2009, has consistently offered a useful service that digitizes "word of mouth" recommendations, allowing you to connect with friends who share your interests in order to find new apps. Now that process is even easier, thanks to the new website, its improved search engine an the new Android app.

Check-in apps are all the rage in the mobile space, but these days users aren't just checking into business and landmarks. Apps like Miso and Facebook's recent acquisition Hot Potato, which allow users to check-in to movies, TV shows, books and other activities, have been part of the fuel behind the recent check-in craze. Another player in the "check-in to anything" game is GetGlue, whose popularity ballooned after the launch of its iPhone app earlier this summer. Today, the startup hopes to build on its success with the release of an Android app, a mobile website and new brand partnerships.

Cross reference a person's Twitter friendships with their Foursquare favorites with their Hunch.com articulated "taste graph" and what do you get? Interesting personalized restaurant recommendations, for one thing.

Taste-gathering startup Hunch is experimenting with a recommendation service that cross references social graph connections on other services with the large set of unusual questions its users have answered. Questions like "do you like facial hair on men? Yes? Well, 48% of our users have said that." The end result is a simple prototype website where you enter a city and your Twitter username and Hunch will show you Foursquare venues it thinks you'll like. Or at least it thinks that people on Hunch who are like your friends on Twitter tend to like those places, on Foursquare. Crazy? Maybe not.

While maybe not the most visually compelling product, Healthful Apps represents an interesting new trend for 2010. Created by Apps for All, the product recommends customer-reviewed iPhone health applications in a variety of categories including autism, relaxation and memory. Although the company's first effort is focused on health, the larger industry-wide question remains - will this year's branded iPhone app be a recommendation app?

Let's say you like RSS feeds. Let's say you're looking for some more good ones to subscribe to so you don't miss good stuff. There are a number of ways to accomplish this, but this week New York based developer Jonathan Christopher built a nice simple new one. Give his app SuggestRSS just a few minutes of your time and it will give you some cool new feeds to subscribe to.

Years after the untimely demise of Share Your OPML and available now, unlike the super feature rich but frozen in private beta service Toluu, Jonathan Christopher's SuggestRSS is easily worth the minimal effort it will take you to try out.
