Tweets that you see that you want to save for the future, whether to give the linked-to article a deeper read or to remember what the tweeter said about a certain subject, you can simply favorite.
Then you can access all your favorites right from your Twitter profile. Which is great.
But what about if you want to save a record of any specific recommendations your tweeps make, and any recommendations that you make? Wouldn’t it be useful to have a single place to store all these nuggets of information, kind of like Evernote or Springpad or Pocket, but instead of for bookmarks and notes, for personalized recommendations of cool stuff to do, see, and read?
