I want to throw this open to readers, If you could change one thing, or have one addition to twitter what would it be?
For me it would probably be html in posts. A lot of people nowerdays link through to interesting blogs or articles which nine times out of ten are a tinyurl link. If html could be used normal <a href> links could then be used, and depending on if Twitter made all links no follow or not, an even greater chance to use Twitter for SEO purposes. Other uses could be to highlight important parts of the 140 character message, for example making some text bold. certainly catches the eye.
But would the html have to count towards the 140 limit? Perhaps, this would make the posts shorter, but maybe more pleasing but it does run the risk of lots of people posting everything they say in bold or italics. Which would get very annoying very quickly.
So for my suggestion it turns out even I have issues with it. So I hope you all can come up with better ones!
