There are people on my home page, in my friend feed, who I do not know and am not following. What the heck? On this page it's tomato_s and haripakorss:

When I looked at twitter.com/home today, my "Currently" status was a block of German text with a tinyURL link leading to a German-language site. What's going on?

Every time I try to change profile, I get "Email must not already be in use" error message. Post claims problem solved, but not for me. Has existed since day I started a few months ago.

I just started following @om, and now when looking at the "older" again all my "older" pages are filled only with @om, and nothing else!

Hi!
I`m using twhirl for twitter and it regularly returns an error "Rate limit exceeded, retry in 5 min". It does this even if it is first time a day.
I`ve visited the page http://twitter.com/account/rate_limit... and it returns me the following
−
<hash>
<remaining-hits type="integer">-456</remaining-hits>
<hourly-limit type="integer">20</hourly-limit>
<reset-time type="datetime">2008-07-01T07:24:26+00:00</reset-time>
<reset-time-in-seconds type="integer">1214897066</reset-time-in-seconds>
</hash>

I`ve waited 10 min and refresh the page
−
<hash>
<remaining-hits type="integer">-608</remaining-hits>
<hourly-limit type="integer">20</hourly-limit>
<reset-time type="datetime">2008-07-01T07:24:26+00:00</reset-time>
<reset-time-in-seconds type="integer">1214897066</reset-time-in-seconds>
</hash>
Actually, I didn`t make any hits at all.
It seems like something is wrong with API functions.
