I just tried out paper.li and I *like* it. It lets you create your own online newspaper using search terms from Twitter. My edition can be found here.
If you choose your search terms well, you can create a valuable reference to mine Twitter information on a particular topic on a daily basis. It also gives a shout out to the people whose content you reference, which is nice.
I am not clear if paper.li archives old copies of your paper. If it does, I will be using it regularly.
