Went and had a look at Twitter this evening with the view to joining to find out what it is all about. First thing I did was check the TOS and read number

3. You are responsible for keeping your password secure.

Nothing unusual in this, I’m pretty sure Gmail, Yahoo and all others say the same.

So why after signing up are we then taken to a screen asking for our web based email addresses; gmail, yahoo, aol etc. and also asked for the passwords?

I wonder how many twitters provided this information and probably broke the TOS of their web based email provider by ding so?
