Thank you very much for your creative work! This has blown my mind and I am sure this project is great use to many steemians.

1. for your second problem, you can always set up a server to cache some results so it is quicker to query than the steem blockchain.
2. I can see from your code there are some duplication e.g. 'what is your username' I am sure this can be refactored into a module.
3. You might want to organize your source code files into different modules for example, utils, steem-utils etc.
4. Unit tests are missing - which is good to add from the start of the project.
5. You can add Vests directly in Steem/Python i.e. you don't need clean. Also you don't need rep_cal as it is already implemented here
