The 1/n 2/n n/n tweets is a huge indicator of a feature need. Of course, that's going to dilute their original value proposition of short direct messages.
SMS has for ages, thanks to Nokia, had the capability of merging multiple messages into a single large one.
Twitter could just make use of this and save themselves a whole lot of grief.
(Before some smartass replies "I do read over sms", well even without sms merging, twitter could still split a tweet into multiple sms. 99.9999% of their userbase wouldn't care.)
"Value proposition" or stubbornly clinging to something that users do their best to work around?
Why not just cut to the chase and make this thing essentially broadcast email, or more generally yet another blogging platform?
Facebook has a complete "Post" blogging mechanism.
Twitter is soon going to stop counting urls in the 140 characters.
One of these things is not like the others...

edit: well, not everyone knows what an Oh By Code is yet, so for now I suppose the link format is best, but eventually, just the code itself will suffice ...
