Are you suggesting that I continually sign in/out of my gmail/twitter
tabs in firefox when I switch between the two?  Yes, that would
enhance my security/privacy (I suppose), but this is not how an
average user functions.

As for "why would a user re-log into twitter [on a phishing site]?"
You could easily put up a fake error message like "Your session has
expired", or "There has been an error, please log in again."

Phishing is not my primary concern for this thread (tho it is still an
issue), my primary concern is with tightly tracking users that visit
sites.  I could keep a list of visitors to my site stored in a
database, or, even more creepy, as soon as anyone landed on my site, I
could send a tweet from some account that says "@user hello! thanks
for dropping by mysite.com! Hope you enjoyed it!"  How many people
*wouldn't* be freaked out by that? (In fact, I should try that and see
what kind of reaction it generates...)

Even sites that have nothing to do with twitter could employ this
technique to learn about their visitors.  At least with normal
tracking/analytic methods there is still an abstraction of anonymity
like an IP address or a location/region.  This just amps the
magnification on the microscope.

I'll blame hammers for sore thumbs when the heads are way too big for the nails.
