I have a list of ping (update) services that I use with Wordpress, but I am not sure how to use it, and if it makes any difference. Does it make sense to sign up to Feedburner by Google, promote feeds etc - I read about it, but I am not sure how it works, and how effective this can be etc.
Thanks for giving the list but for pinging your blog you have to go through mass pinging sites. Just google "blog pinger", you can get good sites like "pingates.com, pingomatic.com etc" which will provide free service. And for wordpress, it is seo friendly. You don't have to do manually to individuals.
