One thought that I have had, is that 3rd party developers can't ADD any more detail to Twitter posts, than what is contained inside the 120 characters, except for maybe location data.
However with the growth of embedding LINKS inside of tweets, would it make sense to develop a Twitter XML Meta data SCHEMA to add meta data INSIDE THE LINK. For example, if the link points to a VIDEO, than the inside the URL, the user could add standard "tweet" meta data explaining to twitter clients that the tweet itself contains a video, that could be directly embedded into a client. I know Google Buzz is doing some "intelligent" dipping into embedded links, but this would establish a Twitter "Standard" for any twitter with a link in it. Therefore, ANY tweet containing an URL, could be quickly queried for the XML metadata, and be able to extract things like a PHOTO, VIDEO, or even widgets, feeds, people, places, etc. You could also include the original full message that exceed the 140 character limit, in the case where a message was truncated from another source. Maybe even a way to embed the required "embed" code so that twitter clients properly display the item inside a client. Is there anything like this already?
