I never have seen spam this bad on ANY forum.
They get hammered by spawn several times a day. In the span of a few minutes the whole board fills up. Its usually dealt with pretty quickly though. You must have just showed up at a bad time. As for bookmarks, yes, its still very much a work in progress. If you'd been here just a few versions back you would have had no bookmarks at all. The feature itself is only a few months old so continue to expect improvements.
Perhaps, haha, you came to the forum to gripe. The Bookmark function is for me, quite reasonable.
We have the possibility of saving sites on the Speed Dial (which permits folders, so you can have a speed dial within each speed dial). you can thus have 100 sites or more saved on the speed dial. There is no other browser with a speed dial that comes close to that.
There is a personal bookmarks bar one can have. One can drag items from the personal bookmarks bar to the speed dial and vice versa.
There are pretty good extensions for a more traditional Opera-type bookmarks vertical display. I have the tidy Bookmarks for chrome extension. Others use different extensions for bookmarks. i forget the names. Opera users can use Opera extensions or Chrome extensions.
And finally there is Stash, for saving short term favorites, or however you want to use it.
And there are notes extensions, where you can save bookmarks. All told, it may not be perfect. Nothing is. But it is a pretty robust bookmarking system.
