I was writing my search engine yesterday and then I realized that just having a bunch of blogs(hundreds or thousands) indexed wouldn’t make for a good website. Because I needed to constantly refresh that information and that would be difficult given my website’s limited bandwidth. So today I decided to research RSS, it does reduce the data amount needed to check for updates somewhat but not as much as one would think. My own blog(front page) has around 18kb, my RSS shows a 8kb page. Another blog that I like to read has the 30kb/10kb ratio. Half as large and 1/3 respectively. Not really that much. They should make a feed that simply shows url and last date modified(or I should discover it, if it already exists). All in all, more useful for its standardization than size saving.
