[Grok-dev] Scalability of annotations?

[Sebastian Ware]

Merry Christmas... no snow in Stockholm, but there are plenty of  
Christmas trees :)

Anyway, I am wondering a bit about the scalability of annotations. If  
I use annotations as an edit history, will I run into scalability  
problems after say 100k edits? Say that each edit requires 5kb of data.

Also, if I used annotations for public comments on say webpages, will  
there be concurrency issues even-though people are commenting  
different articles?
