As Newsvine gets more members and matures, the amount of posts and seeds each member published will only get bigger and bigger. If some people (i.e. me) want to use newsvine as their blog, and I did read a lot of post about that, then we will need our top 5 seeds and posts easily accessbile for our readers.
Just imagine going to read the column of your favorite writer, Miguel, and trying to find that wicked post he wrote on how to free up hard disk space on Mac OS X among 100 posts & 100 seeds... Well, you get the idea!
I guess what I am suggesting is something very simple, based on the number of comments on your seeds and posts that will produce a top 5 seeds and top 5 posts list for when the readers go to your column. Kind of like what is already available with the AP news on the main page of newsvine. Just a simple list.
