I ran some quick stats on the popularity of the various Spanning Salesforce feeds. Not surprisingly, My Unread Leads is the most popular by number of hits.
Interestingly, there's a sharp drop-off between it and the next most popular feed, My Opportunities Closing This Quarter. However, the three opportunities feeds combined roughly match the single leads feed.
Most surprising was the popularity of the New Documents feed, which rivaled that of the opportunities feeds.
The My Unread Leads feed was nearly twelve times as popular as the least popular feed, My Open Escalations.
