not buggy but very unfriendly imo. i don't have an account but i have bookmarked a few. not sure if being logged in makes any difference but my pattern is: click on interesting post, scroll down the comments section, scroll all the way back up so i can click on the "+" sign to get more comments, scroll down to where i left, read some more, go back to the "+" sign, etc...

does not make any sense!

i mean, i put up with it because i don't have an account and well they can decide not to show unregistered people anyone's feed.
