Who reads tweets anyway?
Twitter is missing that content consumption by the consumer is essential to keep people committed to expressing themselves. After all, this is not Facebook, where people can be extroverts and peeping Toms.
Twitter's one-way "take" and lame "give" needs to be revisited soon. And their poor search or TweetDeck needs to cut it. Have you tried to make sense of what's up by reading tweet searches line by line? Fun right?
This is why I developed tweetzup.com. Let anyone know what's up meaningfully without having to read many tweets. The collective emergence of trends focused on what you care about is more revealing than reading everything and wasting time. Furthermore, you can set tweetup alerts about keywords that are trending on the topics you follow. And yes, tweetup can tweet the watch for you.
Let the machine service the human. Not the other way around. Sorry Twitter, but it is time to think about giving back to the people instead of expecting them to express themselves, knowing very well that their individuality has next to zero chance of being noticed without a ridiculous amount of promotional effort.
That being said, Twitter is also a great channel for targeted campaign or event communication. In this context, it serves as an open communication utility for a short period. And that is very useful.
