I was wondering; for website URLs we got Google, Yahoo, DMOZ and a few others considered to dominate the SE world. Could anyone recommend me the best sites for RSS submission? I have come across of dozens of these sites, but haven't a clue which ones are really the most popular.
Something else; I know I do not have to resubmit the RSS url every time I add new items to it, but how often does it get crawled for new items? Is that defined by the 'lastBuildDate' tag? Found this useful list of RSS tags at: http://www.make-rss-feeds.com/rss-tags.htm

I am pretty sure that is up to the reader. Most RSS readers if being viewed in an HTML page will use HTTP request to request the XML file. So really it is up to the reader. Some may have a property you can set to have it check every X minutes.
I know that the google/ig page that has the RSS reader seems to check different feeds at different times so it may base it on the freq. property you mentioned.
According to Yahoo, they check your RSS at the beginning and judge how often it is updated - but it checks back a minimum of once a day. I think they define updated as a new item in the RSS and take no notice of any LastPub or LastBuildDate.
By the way to get your RSS into MyYahoo (I've got more than a thousand so I have long experience on this)-
1 sign up to Yahoo mail 2 Put a MyYahoo link on your page (see yahoo syndication help) 3 Click on the MyYahoo button (click twice if it says not found) 4 Don't worry that it doesn't have the title/items 5 Next day, add a new item 6 Wait till it's spidered - it should by now have items in it and a link in the title
With MyMSN (once you have an account), enter the url of the RSS feed in add content. It then sends a spider out. About 10 minutes later try again - it should work then. If it doesn't try again 20 minutes later
