Well it's not overload, it's redundancy! When an information link fails you still have plenty of others ~~laugh~~. 

For example I have subscribed plenty of rss feeds and mailing lists... Most of the times I just browse through the titles, maybe 1 in each 20 or even 30 calls my attention... So I don't actually get overloaded. And to be truth I never had that overload headache, maybe it's just me!
