Looking at your profile, you're currently subscribed to two OpenID accounts. Unfortunately, OpenID accounts can't post entries. And, as mentioned, the ability to read Livejournal posts on your Dreamwidth reading page has not yet been implemented.

I see, though, that you have a bigger access list. Dreamwidth has split the Livejournal concept of "friend" in half. Here, you have an "access list" of people who can see your locked entries and a separate "subscription list" of people whose entries you want on your reading page. So, if you want to follow those other journals, you'll have to subscribe to them as well as giving access. You can do that by visiting their journals, hovering your mouse over their userpics, going to your "manage circle" page, or any of a number of other ways.

Does that make sense?
