Few ideas to evolve metafora

- Geo Tagging of tweets, I can see all tweets coming from nearby me. ( To maintain the anonymity the geotaging should be accurate only in 5 kilometre circle )
- Topic based tweet - Each tweet i can link with a list of pre approved list of topics
Like for example _ Coinpicking can be a topic.

- Visibility of a tweet must be based on the author of the tweet and his reputation in the domain. So eventually if my reputation in coinpicking topic increases then my tweets will be most visible in the domain of coinpicking.
