I just trying feed agregator at feedburner. This sites provides feed agregator service for us, this services work to save our bandwidth hosting. i.e if we have a sites with many article but if any others want to subscribe to our blog, we just pointing our rss feeds to our feedburner rss feed agregator.
This service can save our bandwidth at bloghosting provider, cause all our rss services is pointed to feedburner. I just trying with my blog rss feed at blog.nawi.web.id and I got this feed address.
I recommend this service to any other blogger to use this service if you are using own bloghosting provider.
