There are many niggle things about Twitter, one of which is when someone asks for something to be “retweeted”. When that happens I not only get the original, but others post the same thing again and again.
Retweeting can be a really useful thing and I am not discouraging it. I would say don’t just retweet just because someone asks, do it because you want to tell your followers, but other than that I would encourage it. It can result in people outside your direct Twitter circle finding out about something they will find interesting or useful.
I have had an idea to solve this. No, stop, come back, it might be a good idea for once. Why not implement a retweet feature in Twitter. It could work in a not to dissimilar way as favouriting a tweet. The difference is when a friend, or several of your friends flag it for retweeting it will appear once in your stream.
The only technical problem I can see is that if the tweet is not flagged for retweeting straight away the tweet could get berried in the past and missed. There are obvious UI solutions to this, and I would look at aliasing the original tweet each time, but with Twitters scalability problems this solutions need to be really really simple to implement.
Please do post any thoughts here, or on Twitter.
