While Twitter is actually the one service I don’t lose sleep over missing reading every single item — I think because I recognize this would be absolutely impossible, whereas on services like Tumblr, it’s possible for me to read my entire feed each day (though a lot of work) — I do agree with Mat Honan on this:
Discover needs to get far better at surfacing the most interesting things from your own timeline that happened since you last looked at Twitter. Imagine if instead of showing interesting things from all around Twitter, Discover focused on your own timeline and showed you the most interesting and important things since you last checked Twitter. It could display the tweets by people you follow that were the most retweeted and the most favorited. It could show the links that came up the most often over the past hour (or two hours, or four hours or whatever) on your timeline, or that had people talking. If two or three of the people you follow message each other back and forth for multiple tweets, it should put that conversation in front of you, starting with the first tweet (especially if more people join in).
What’s he’s asking for is not just a more personalized Discover, it’s a completely personalized Discover, made up of only content you follow. It reminds me of the old “Best of” areas of FriendFeed. If you weren’t living on the service 24/7, you could get the best elements from your feed from the past day, week, or month. I would love to see Twitter implement something similar. Certainly, they have the signals (retweets, favs, replies, etc) to do so.
