>-Click on their name, click on "posts" or "comments" depending on which you would like to see. You can also see what they've "shared". This handles your first paragraph.

Missed that sorry. I will still say if I refer to say your post page(http://hubski.com/posts?id=thenewgreen) In the sidebar maybe say that I'm viewing your post and give a nav option to view your comments and other info from right there instead of having to click on your name again somewhere on the page and then waiting for the pop-up and then clicking again and waiting for the page to load.

You can streamline a step or two out of that with some slightly better navigation. Also while I'm on it if you move some of that user info on the post page to the sidebar give the option to follow them in there with their sorting information since a lot of people are probably going to decide to follow a user based on their post.

>Click on "tabs" under the link. Is this what you mean?

Sort of. I mean that does work. I'd like to just be able to click on the external link and have it auto open in a new tab via a user configured setting rather than having to click over to the new tab link. That said not to big of a deal because you have the tab link and I can just click center on the scroll wheel.

>The lack of a time signature in your feed is intentional. If a subject is interesting, why wouldn't it be worth commenting on regardless of when it was posted?

There is something to be said for that. At the same time news events can somtimes move quickly and the topic can still be interesting but knowing how long ago the headline/thing was posted can be helpful because it might mean you want to go hunting for a newer post with newer info. I can take it or leave it with the lack of time stamps however.
