what is the use of rss feeds. can you tell me.

1. User can subscibe the content even to mobiles.
2. You and somebody else can integrate the content to your other profiles and other sites.
3. Content aggregators can list your content.
4. You can submit your content to agregation services like technorati, diggit, etc.

So, if you are producing freguently new content RSS feed will be essential to get readers.
