Tweetr - Tweet Markdown, Instant or Schedule

My new project (no Business mode yet, so I do not want to call it product) is finished.
With Tweetr (https://tweetr.me) you can write markdown and than tweet it. Tweetr handles the formating and also the scheduling for you :D

Do you folks find that usefull? Are you going to use it?
And most important: Do you have any idea how I could monetize this (apart from ads on the site)?

Thanks so much for you feedback <3
