This sounds exactly like Read It Later. I don't know what the differences are between the two, but it's an alternative if you're looking for something like this. Anyway, my experience with this sort of thing is that I never feel like reading all the momentarily-interesting things I discover when I come back to them later. I think that by putting it off, you place reading about an interesting idea into the "this is something you want to put off for later" mind category and it never gets read, or at least that's what it felt like in my experience.
Read It Later used to (further) ruin my attention span until I uninstalled it. I would only read blog snippets and forum posts which were too short to bother delaying, whereas substantial articles and papers all ended up RIL'd into oblivion.
A lot of times you may come upon a juicy-smelling "information scent". Now you have a decision of whether to extend your lunch break and cut into work by following the scent (bad) or abandoning it (painful, and possibly bad).
One thing that has worked for me is using either delicious or more recently instapaper app to save the link (instapaper will actually sync the entire article back your iphone/pad/android). Pang of pain is largely avoided, and I can decide later whether this bit of info was worth reading, by comparing it to my other saved articles in the app at the appropriate time.
