you are doing an amazing job. And for me personally it would add another layer of security and service, if you could add a little preview of a link attached to a tweet. It is common (and Facebook made it accepted) to show what is behind a link. So here is the question: could you read OpenGraph tags to show a little preview of a shared link right below the detailed view of a tweet on your website (like you do it already with other Twitter accounts)?
This would be really nice.
P.S.: Of course you can do it on your own, I am sure on this. But in the case you need help or just want to talk, do not hesitate to contact me whenever you want!
