Interesting indeed. I started using FeedDemon because I grew tired of having my RSS in Outlook (I do not think RSS belongs there for high volume RSS readers). Before using FeedDemon though I was using NewsGator Online, and then added FeedDemon because while I liked the benefits of online I did want a single offline client that sync'ed to NewsGator Online and well FeedDemon does this.
Congrats to Greg and Nick on the deal. I think it will result in really positive outcomes for both sides of the deal (and the customer, me!).
