If you can believe it, I just discovered Blaq yesterday. I have been using the stock twitter app on my playbook and it didn't occur to me that there was such a great alternative. I was so frustrated with missing tweets and being stuck on 1 day feeds and having to refresh constantly to get it to show current feed, that I actually tweeted my frustration and 2 people immediately replied (thanks to email notifications or I wouldn’t have seen them ) telling me to check out Blaq. Whoa, blow me down and call me dusty, where have I been? I went in search of it, found it, bought it and now will never give it up. It's that good. If you're on twitter and are not using it, what are you waiting for?
