Has anyone used paper.li for their twitter feeds...if so, what are your thoughts?

I recently decided to determine for myself the benefits of a twitter account that I regularly check. I also discovered a free service called paper.li, which essentially aggregates a person’s twitter feeds into a newspaper format, organizing them into subjects and making the feeds visual when they reference online articles.

Have people used this service? What are your thoughts?

If there are any other news and feed aggregators that one finds better or more comprehensive, please also share.

PLEASE NOTE – this thread is about news/feed aggregators generally at the most broad – please stay on topic if at all possible.
