Summary: there are several twitter clients. Some show more information and some show less, but you can easily switch between them!

I still don't understand why this and other articles from that site (daringfireball) are popular.

Someone once said "Twitter clients are the 'hello world' of Web 2.0"

(or something along those lines. I forget who)

edit: well, lots of people have said it, actually: http://www.google.com/search?q=%22twitter+client%22+%22hello...

A concept I took from the article was how interesting it is to see what people come up with using the API of what is at heart a simple service. I may be bias as this is my personal view of course :)

Wow, lots of words and nothing insightful to say. Gasp! Apps that use APIs don't have settings to export and enable developers to be creative!
