So I log in and the first obvious difference is that I can see exactly four bookmarks on the screen at once. And if I scroll I see that there are only 10 per page. Don't you think that's a bit sparse?
I'm not sure what use case the new owners think most people are on the site for, but for me it's to save bookmarks and quickly find them again. I used to have a nice tall list that I could scan down quickly.
So I click a tag off the sidebar to narrow things down a bit. Nine Mississippi. Ten Mississippi, and I came back here to update my comment. I can see the other tab still spinning.
Searching came back fast enough, but really, I don't want to have to type keywords in to find links that a few days ago were in a nice tight list on a single screen.
In all, this seems like a huge step backward.
Beyond that, the homepage seems to have changed. I've never used the homepage, so I can't comment on whether that's an improvement or not. Anybody know what the homepage is supposed to be for? Looking at other people's bookmarks?
