Anyone who's in a position to use Tweetdeck instead of Twitter's web UI will find a free, Twitter-maintained, product with no annoying algorithms and no advertising.
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?
