No, they don't care about commenting on Mini-Feed entries. - Aaron Myers

Seriously. There are thousands of people trying to bite or zombie attack one another on a daily basis on FB. I'm not sure useful matters all that much. - Kate from FriendFeed MT Plugin

I use this all the time, but it's inconvenient to have to visit everyone's profile to use it. I should be able to comment on anything from Facebook's home page. It's a great feature because I can comment on a new status or addition to someone's profile, and they know exactly what I am referring to, instead of needing to ask me sometimes, it also allows us to start a thread when referring to the same thing. My non-ubergeeky friends have also grabbed hold of it now that it is clearly known to be a commenting feature, and have become more engaged in Facebook use with it. - Shawn Kirsch from FriendFeed MT Plugin

Those mini-feeds are really too small for me to notice with all the other feeds. Maybe, it's a habit of scanning tweets for so long that I often ignore the tiny print and go staight to the wall to get a message across. Which gives me an idea for a good Wall app - Wall-E!

Literally in the last week I have noticed a number of my less geeky friends on Fb using the comment feature on everything from pics to my status... For people using Twitter and Friendfeed all the time, the Fb comment implementation is less than awesome. For more normal people, it certainly boosts the conversation quotient of Fb. - Clay Newton from FriendFeed MT Plugin
