Let's aggregate 'em all!

I predicted in this very year that this year will be devoted to aggregators and this is indeed becoming half true. I delibrately used half true for a reason, because tI havent seen one very good use in aggregation space. As we are jumping into media stream we will surely feel need of aggregation and the most crisp and faster aggregator will suffice our needs.
There are hundred of social video sites with web space getin youtube clones every second day and few Flickr brothers every day. And you will after reading their reviews on blogs like this will go and make an account in them and might just upload a photo or too and then put your name in few groups in those web apps. But slowly and slowly you will stop using them but that might not be true for others and they might still be updating their stuff. Now if you have aggregators then you will have one site for viewing every stuff. But hey wait a second...isnt Google reader doing same thing and might just do it in better manner. So whats the use of having specific video aggregator or photo agregators.
Sorry friends I am in no mood to burn my mind in this case as I see no use and I will try not to cover clones, but still clones are important, as it might inspire the original one to break the shakles of normality. If you have any answer for this problem then do tell me. But i still believe that aggregators are out there to make it big.
