[Tutor] suggestions for read unread items datastructure

[Alan Gauld]

Caveat - I know nothing about RSS, it's one of those web 
technologies that I just can't get excited about, sorry...

However...

Whenever you need to maintain data for "a huge number of users"
its time to question whether it's your job to maintain the data. 
Maybe the users should each maintain their own data? That's 
the idea behind cookies in a web browsing context - does 
anything similar work for RSS?
