hi balladeer, the invite is created by my pub (a peer that has a public ip address and is always online), when you use the invite:
- the pub will post a message to follow you
- you will post a message to follow the pub
- you will post a message advertising the pub on your feed
basically this mean you will become connected to the pub's social graph (by following the pub) and vise versa the pub will replicate your messages (by the pub following you).
also to note, in the future we will change the pub invite story: invites are directed from one user to another user and pubs are only a messenger (%LMYARKcJ5/HVrkfyGo0oSV4j/whFmpeiJlQnvPw53PE=.sha256), and pubs will become just another device controlled by a specific user (%Gwqklkj0b2CBT5tPiz5170NWsPp3xiuLbOImEaG/e+4=.sha256)
happy to answer any questions! also, i know the initial sync is pretty intense at the moment (joining most public pubs means joining an active community with years of content!), but once it's done it's done, later you only sync what you missed since you last sync'd.
