Nests a while back took 3 people to make a room visible so people could know you were there. (Pain to start and get people in a room unless you sent a lot of notes and invites.
Lots of audio glitches. No developer around to help.
Jam systems had updates that nests did not update.
The implementation of nests (from Jam systems) was closed source and people could not build upon nests to add tweeks.
Most have migrated to corny chat as the developer is almost always there and helpful.
Much funner environment.
I recommend using both and checking them out sometime, if you really want to know what they are about.
Social engagement is wise. Instead of just writing code and expecting someone to just use the code.
Implementing lightning tips for all users in corny chat is so nice also.
(Nests you only tip one developer)
So many new upgrades on a daily basis now.
