I ought to be reading my brand spanking textbook, but I have a bee in my bonnet again and I can't concentrate on anything else.
Xanga has recently released several new features. One, the ability to turn off your site's RSS feed, is under the Privacy heading in the account settings. This in inaccurate. Not publishing a feed does not make your information any more private. The only thing not publishing a feed does is make it harder for geeky feed consumers (such as yours truly) to stay abreast of your site.
An RSS feed is a stripped-down version of your recent entries. Anyone can use an RSS aggregator to get notified of entries to any site that publishes an RSS feed. Livejournal's syndicated accounts use RSS feeds. My personal aggregator is Bloglines; I love it because it's web-based, so I don't have to install anything and I don't have to sync subscriptions across the several computers I use. Because I'm most familiar with Bloglines, I'll use it in my examples.
An aggregator will check all the RSS feeds it read regularly, usually somewhere from every thirty minutes to every two hours. I believe Bloglines is closer to the half-hour mark. This does not mean that Bloglines is a stalker, obsessively checking your site for updates and details! Bloglines is just dropping by on schedule. When it sees no updates, it just kinda shrugs, says "Cool," and plans to come back later. The reason it checks so often is so that I, and other Bloglines users, can know about new posts very quickly. If it only checked once a day, I might not know about a new post until 23 hours after it's been made! Because it checks hourly (or thereabouts), I can be sure that I've read everything posted within the last hour (assuming I read my subs in timely fashion, but that's a Ree thing not an RSS thing).
Bloglines needs RSS feeds to work it magic. If I am subscribed to a site that has turned off its RSS feed, I no longer get updates from that site. I have over 200 subs in Bloglines -- if you turn your site off, I
will forget to check for updates, because I remember to check all those sites every day. That's
why I use Bloglines!
So it sucks that Xanga permits people to turn off their feed without even informing their users what an RSS feed
is. I imagine many people have turned off their feed simply because all they know about it is that they don't use it themselves. The problem is that an RSS feed isn't for the site owner's use; it's for their readers, and it's the RSS-savvy readers who get boned from use of this feature.
There are circumstances where the RSS lock may make sense. In particular, if you use the Xanga Lock so that only signed-in Xanga users can view your site, turning off your feed makes sure that non-Xangans can't see anything of your site without signing in. However, if you're letting random visitors in, there's nothing to be gained by removing a handy feature like an RSS feed. Please leave it on unless you have a reason to turn it off.

Nobody who's turned their feed off has bothered to read this far, have they? Dammit. I'm totally wasting my time.
