if you really want a good social bookmarking system, then go for premium paid service, they are good the one like bookmarkingdemon it definitely does a great service
Automatic is easier, but like others have said, you reap more benefits doing it by hand. After a month you already have 30 if you do just ONE per day!
If you are the lazy type and have the cash to purchase auto social bookmarking submitter software, then by all means get a hold of automated submitter.
The only implication with this is that, if the site owner of a certain social bookmarking site decides to change the site then the social submitter can no longer have the brain to adjust to the current S.B. site.
If some peeps can code a software of these submitters that have Artificial Intelligence in them then it would be the best thing in the website promotion world.
socialmarker is good but it's not auto tool. i think you should do it by hand. slow but good result
i would recommend you to do it manually for better results
anyone here has any experience with autopligg?
Here's an idea to make some of your social bookmarking automated, but it does require that you have an rss feed for your blog.
1. Join Ping.fm (it's free) and when you join you'll have about 50 social bookmarking sites it's connected to that you can post to.
2. Sign up with at least 1 or 2, like Twitter, Bebo or whatever...
3. Then go get a free account with TwitterFeed.com, although you don't connect it to your twitter account. Instead, use it to forward your rss feed to Ping.fm, here are instructions on how to do that on the TwitterFeed blog.
4. Go back to Ping.fm and sign up for the rest of the bookmarking sites.
What happens after you do this, is every time you write a post on your blog with the rss feed you submitted, it will automatically be sent to all the social bookmarking sites.
