Thank you for your answer.
I have been considering the second option, but the problem is that I have an anchor with the twitter’s href and when the user clicks it, it shows the tweet form in a separated dialog/iframe, so I can not access it to change the Tweet button’s method and override it with the statuses/update endpoint.
Do you know if there is a way to avoid creating myself a “Tweet form” like the one in the dialog and access the one Twitter creates? Or there is any other solution?
Thanks again
