First off re-searchr got a little more social. Going off my theory that social search, and searching socially are different things,
I added some features for searching socially. Briefly, searching socially if a passive thing where your search results can be altered by algorithimic re-ranking based on your social network (and what they have said about various websites). For re-searchr, once you register and add in your social network credentials, re-searchr will use the number of comments and content of the comments from your network for a search result url in its re-ranking of your searches. The re-ranking occurs for searches at re-searchr as well as using the re-searchr toolbar to follow your searches on Google, Yahoo, MSN and Ask.
Secondly re-searchr got an addition to

Third re-search got sentiment analysis. As you can see in the picture above each comment is labeled either with a smiley face (good sentiment), a blank face (no sentiment), or bad sentiment (frowny face). The sentiments are also rolled up and shown in the meta-data next to the search result urls. The sentiments are used to affect the ranking of the search result, in the same vein as above, sentiment data from your social networks has much more effect on rankings than random sentiment.
Finally re-search has started using GetSatisfaction to manage any problems, issues, or ideas that anyone has with the system. This service is much better than the old contact page/system, so I encourage everyone to leave feedback whenever something breaks, or with ideas on how to improve things on the site.
