I would like to share an idea that always and everyday i need it hardly as an option in twitter.
when i am following many users, i face sometimes an enormous amount of tweets that are wast of time for me, redundant or silly, what so ever. Meanwhile i want to keep those who i follow. There are only 2 option in twitter to stop some of those unwanted tweets (block user or block re-tweets).
What about adding an option to block all tweets that include a keyword. For example, when Real Madrid won a game, i will receive thousands of tweets and retweets on that subject. This will make it difficult to read the good tweets from others.
I hope my idea is clear. I think it is not difficult to program that and add it as an option for users to use it when ever they need it.
