Another week, another milestone. Yes, just like clockwork nearly every two-weeks the Marketplace adds another 1,000 apps to its belt (5K was on 12/28/10).
The good news is development doesn't seem to be slowing (20K+ developers on board now), then again, it doesn't seem to be growing more rapidly either. However, Microsoft's app approval system may be fixed to only be able to push out 1k every two weeks and not really anymore. It's all a mystery to us.
Regardless, at this rate we should hit 10,000 apps by the second week in March at which point we'll have a party or something. All we know is we're leaving WebOS in our dust and our next goal is to beat BlackBerry (16K apps). See previous 5,000 post here with each previous 1,000 documented.
