RSS (Really Simple Syndication) and news feeds are hardly new. Do a search on Google for "RSS" or "news feeds" and you will find articles telling of its history that goes back to the pre-millennial days in the late '90s. You may also find results that point you to where you can get help understanding this phenomenon that is a little hard to grasp at first. Finding web sites where you can download "news aggregators" or "readers" of which there are a plethora will be a breeze.
Here is the best summary I can give you based on my
current understanding of the concept:
- Is it E-mail? No. Not really. Although some news readers present news feeds as such.
- Is it a mailing list? No again. This question is somewhat related to the previous question. If it's not e-mail then it can't be a mailing list per se... but it can replace one of the reasons mailing lists are used in the first place. Mailing lists have been used to notify users of web sites that content has changed or the way you browse that web site has been updated. (At the company where I work, I'm currently trying to convince colleagues to jump on this bandwagon for that very reason. I really don't want to manage a list of e-mail addresses and then e-mail messages to notify users that we have changed something one of our internal web sites)
- Is it a subscription service? Not quite. Although with a news reader you do subscribe to news feeds.
- Well what is it then? It is a very low tech way of publishing content that requires the "subscriber" via a news reader to regularly check a particular file on a web site for changes. This specially formatted file (or files depending on the intended audience) contains the same types of information that is necessary to describe an e-mail message. (i.e. Author, Title, Date Published, Body translates to From, Subject, Date, Body of message)
Pros - With a news reader that looks and feels much like an E-mail application (whether desktop or web based), you, as the subscriber, have complete control over the feeds to which you subscribe. Whereas with E-mail if you are on some mailing list and it becomes spam to you or was spam from the get-go, trying to unsubscribe may not always work. Alternatively, attempting to unsubscribe may notify the sender that your E-mail address does exist and you may end up receiving more junk than you did before.
- This means a little more accountability for the content provider. For example, if the content provider decides to begin putting advertisements and marketing in their feed(s) they may risk losing you as a subscriber. All it takes is deleting that feed in your browser if you are not satisfied. No worrying about confirming your E-mail address to spammers or hoping you'll be unsubscribed from this annoying mailing list.
- Changing your e-mail address and then notifying all of the web sites to which you have created accounts is a thing of the past. Subscribing to feeds doesn't require keeping your E-mail address updated. In fact feeds don't use E-mail at all.
Cons - You must have a reader to subscribe to the feeds. They are not yet commonplace. But I anticipate that they will be soon.
- Subscribing to a feed is not as simple as clicking on a link. In fact if you click on the little orange XML image on a web page you will most likely see cryptic tags describing the feed contents that only a reader can display properly to you. Often you have to copy the address of the feed into your news reader to subscribe. There are several ways to do this but it is not straightforward to a beginner. However some news readers add plug-ins into your browser and scan each page for possible feeds as you browse the web. If you come across a page that may contain a link to feeds you can click on the readers button to see a list of feeds and then subscribe right from your browser window. Online news aggregation services exist that offer free aggregation of feeds you choose.
I'm sure I've left out a few more important points but I highly recommend downloading a news reader and trying out news feeds on some of your favorite web sites or blogs like this one.
