One of the complaints often directed at blogging is that not everyone is a blogger - not everyone has the interest, time or the skills to write for others.
While glancing through Furl's Popular List , I realized how effective it could be as a learning tool. Anyone can use Furl (it simply stores a copy of a webpage in your user folder, so pages aren't lost or links broken). Making connections is a knowledge era skill. Imagine a group of 25 students subscribing to each others online topics of interest (Furl folders can be public or private)...gaining insight into what other classmates found interesting enough to keep.
