We certainly do eat our own dog food and it tastes great. We use Readmine reguarly throughout the day. Actually without Readmine I would be lost - each time I load it up and click the next unread button (at the top right of the small toolbar) I'm straight into the news that is interesting to me. And that is with 1900 items on the list. I'm clicking through items that are really interesting - stuff I need to know about and I'm not having to trawl through endless meanlingess items that I dont care about. The Readmine install I am using - i never put in any important words - I simply did a quick install let it read my browser cache and then just started reading with it.
I've also been finding stuff that i had been discussing with friends - within minutes - and I am able to instantly drag and drop relevant stuff to my friends and voila!
