No matter how many times I click "Show less of this" it keeps coming back.
It's the version of Twitter targeted at newsrooms, etc.
I assume a lot of people already know and have reasons why they don't... but likely not everyone here has tried it so it may be worth repeating.
I had heard of Tweetdeck, but I assumed that it was a third-party client which provided a better experience and was therefore at odds with Twitter's interests. You're telling me that, not only is Twitter okay with it, but that they built it?
It was independent then Twitter bought it.
There were alternatives before such as Seesmic, no idea how they work now, if they still do.
