The fun part aside, are there any real use cases for tweetbymail?
At the peak of .Com days, there was a startup that promised to bridge e-mail and snail mail: one can use their service to email people who don't have an email account or connectivity, and it would be delivered through snail mail.
How do multi-byte Unicode characters work over SMS? Languages that use an average of four bytes per character can only send 35 character messages? I'm not so sure "fair" is really part of the discussion. Twitter still has SMS turned on in some countries that use wide characters, right?
There is no argument, I'd like to know how they handle it. Since I don't use a language that uses a lot of wide characters, nor do I use twitter via SMS (I barely use my twitter account as it is), I'm interested as to what the experience is.
