Lean Domain Search, despite almost no work since its acquisition by Automattic two years ago, has continued to thrive, now handling more than 160,000 searches per month:
It’s monthly growth rate works out to be about 6.5%. Not huge, but not bad for maintenance mode. :)
I think its growth is still driven almost entirely by word of mouth so if you’ve ever shared it with anyone (I’m looking at you, Jay Neely), thanks!

Looks to me like getting put into maintenance mode was the best thing that could have happened to it :)
Haha, you joke, but if I kept working on it I probably would have added a bunch of features no one cared about, making it complex and hard to use in the process, hurting its long term growth. The trick is knowing when that’s the case and when it’s not… :)
Well deserved growth Matt! :)
Thanks Adam!
