Twitter has acquired Bagcheck for an undisclosed sum. Bagcheck engineer and co-founder Sam Pullara is also along for the ride, as he is joining Twitter’s engineer team as part of the acquisition.

Bagcheck is a service that lets users make lists of stuff they use and share them with others. Users have been able to use it with Facebook or Twitter. Here’s how it’s described on the about page:

Whether it’s computing, photography, cooking, or sports —we all have a set of favorite items for doing what we love. Bagcheck is a fun way to share and discover what’s inside our “bags”.

Bagcheck was started by a few geeks who love their gear. We realized we’re not the only ones that spent lots of time discussing the products we love to use. So we made Bagcheck to allow people to talk about and share lists of the stuff they use and why.

“Bagcheck will continue to be available,” said Pullara on the Bagcheck blog. “That means all the great content you’ve made is staying online at the same URLs and will still be searchable, sharable, and lovable. But as with any acquisition, things may change at some point in the future, so if you’re worried about your content we’ve also created an instant export feature that will wrap all the bags you’ve made into a tidy set of HTML and JSON files. You can export all your content using this feature on your profile page and post or save your bags anywhere you like.”

Co-founder Luke Wroblewski meanwhile, will move on to different pastures. “As far as me… only time will tell what’s next,” he wrote on his own blog, noting that Bagcheck is in “good hands.”

Just what Twitter has planned for the acquisition remains to be seen.

The company did recently acquire a new round of funding, which it said would be used for innovation, hiring and expansion.
