But if size is an issue ...

...and it is for me, then all the more reason to consider a forum 
style message board.  I can't all read all the messages every day.  
There are only so many hours in the day.  Refining my interests can 
help me to focus.  I know it's unusual, but I belong to a thriving 
forum of well over 10,000 members and growing.  It works beautifully 
even with this large membership.  And the only emails I get mailed 
to me are from threads to which I have subscribed, so I do have to 
scan for new threads often.  That way I can keep up with the new 
material.
