Bookmarking Daemon is the most powerful for professionell Social Bookmarking. It’s the only Social Bookmark Submitter Software which provides to create Accounts. Full automaticly. So you build a huge list of Social Bookmarking Account.
The next powerful feature is that you can easily add other Scuttle, ScuttlePlus and Pligg Sites. Even if they use Captchas. There are many Sites you can add to Bookmarking Daemon. Most of them don’t mark their Links as NoFollow.
Next to say is that there are many provided Social Bookmarking Sites as mister-wong, delicious, folkd and many other major sites. It’s far better than Ssubmitter with its submission succes. Almost 90% succesrate is normal. If you every used another Social Bookmarking Submitter Software than you it’s not normal 
Bookmarking Daemon is a MustHave for every internet marketer, because Daemon saves you more than much time.
There are some alternatives to Bookmarking Daemon, but none reach the succesrate of Daemon.
