Finally, Twitter is building stuff again

The other thing I missed yesterday was Twitter’s soft launch of new activity streams.

I haven’t had a chance to try them out yet, but they look interesting. This feature made Facebook a lot more addictive, and I’ve found it useful on Instagram, too, so maybe it’ll be a nice new way to look at Twitter. (And it could get me onto Twitter’s website more often, instead of just using TweetDeck, which continues to feel like a 2008 Adobe AIR app.)

Most importantly, Twitter is finally building stuff again. This is the strongest product development push I’ve seen coming out of Twitter since… ever, basically. It seemed like a couple of years went by and the only things that happened were boring lists, the retweet function, a few homepage redesigns, and a lot of TV appearances. (Okay, Twitter did become a lot more reliable, which was important. But that can’t be the only thing you do.)

Now, under founder Jack Dorsey — who is leading product development — and CEO Dick Costolo, Twitter really seems to be moving quicker, making strides in product and revenue design. The danger is doing things too quickly, or changing things too drastically, but I trust Jack not to do that.

This is good.
