I found a great article submission services sites http://www.isnare.com/ and http://articlemarketer.com./index.php. They say a great way to get lots of backlinks to your site is through article submission. I have heard of article submission services like isnare.com and articlemarketer.com. is good and fast.
Does any one have any experience (good or bad) in using either of the two, or in using other article submission services?
Do you think it is still better to submit articles manually?
