How neat wouldn't it be if we could filter Top Stories by:
- Now (as it is ..now)
- Past Week
- Past Month
- And maybe All Time
The infamous "fear of missing out" would be considerably smaller for many including myself, since you can rewind the most important stories for the past week etc.
Regarding if it would actually make the "feared" users drop in daily traffic, ill doubt it.. and even then it would still be a "user first" feature to implement.
