Social bookmarking could be exhausting?

If you are obliged to do social bookmarking on SEO services, would it be exhausting? I can say yes or no. Why is that?

Yes - if you don't have accounts yet like Digg, Technorati, StumbleUpon, Squidoo, Delicious and other social bookmarks, you need to create one and post or submit your site to them. Mostly social bookmarks in my list are inactive, so if you're a newbie, you might find it hard to search the do-follow social bookmarks.

No - if you already have accounts on social bookmarking sites, unless you're banned and removed due to spam, it's an advantage. Much better if you create accounts on the social bookmark list you have stored before attempting to auction your services as a social bookmarker.

I hope it gives you an idea. Might be exhausting but worth for my time.
