Depending on the workplace circles you travel you may have heard the term "Jelly" tossed about. As in "Will I see you at the Jelly at Bob's place next week?", Or "I've decided to host a Jelly at my loft every other tuesday - drop in!" No, it has nothing to do with toast. Or at least toast is optional..
I can't find a strict definition, but my take on it from what I've read is that a Jelly is a loosely structured work get together hosted at a particular dwelling or studio space on a regular or scheduled basis, although it seems sometimes they form spontaneously. Its like a work party, not to paint your place, but for people to bring their own work to do for a day at your place. At a Jelly friends, associates, all generally independent workers, will drop in to the designated location to work and/or to collaborate. The idea is that the participants will gain the benefits of interaction with colleagues, the elimination of distractions they may have working at home, or just a more studious environment coming from your focused coworkers - the library reading room effect! We've seen this same relationship to coffee shop working, and CoWorking entities. But also this seems to generate a fresh focus for the independent worker, where the new workplace situation may actually help them experience greater productivity. I know I've experienced this phenomenon when forced to work in ad hoc situations, while traveling, or waiting, suddenly there is a reservoir of focus on hand. Some Jellys go on to develop into a CoWorking collective reinforcing the argument that the community often exists before the CoWorking site does.
But that is just my limited perceptions. I'd love to hear more from Jelly participants in the comments. Also here is an article on Jellys from the UK's On Office magazine - link.
