From the jotpsot.com press release:

We’re writing to let you know that Google has acquired JotSpot. We believe this is great news for our users. More importantly, we want to reassure you that you’ll continue to have uninterrupted access to your account. Both Google and JotSpot are committed to supporting our customers, and we understand that users have invested a lot in our products. In the near-term, we’re focused on migrating JotSpot to Google’s systems and datacenters. We’ll work hard to make that move as seamless as possible so that customers won’t be inconvenienced.

Why is Google acquiring JotSpot?

Google shares JotSpot’s vision for helping people collaborate, share and work together online. JotSpot’s team and technology are a strong fit with existing Google products like Google Docs & Spreadsheets and Google Groups.

Certainly this acquisition makes sense to round out Googles on line application suite and should really elevate Wiki technology into the main stream. This is one more tool that can help small businesses function on the internet. You can read the details here.
