Who takes care of your social media marketing strategy?

Do you outsource the service or do you take care of it yourself?

I do it mostly myself, but might outsource social bookmarking if want a lot of it doing.

I also want to outsource social bookmarking,even though i have much time but i don't know how to extend it .

Try using fiverr or odesk. I have a great person that does 1000 directory submissions for me for $50. And was $15 for 100 social bookmarkings.
