In these few day, just study RSS tutorial and found some concept question for RSS advantage
from this BBC NEWS link at http://www.bbc.co.uk/news/10628494 that it mention
"News feeds allow you to see when websites have added new content. You can get the latest headlines and video in one place, as soon as it's published, without having to visit the websites you have taken the feed from".

So I try to add new RSS feed for BBC NEW feed in my wordpress, and it shows the following
page attached. I can see the RSS icon and BBC NEWS feed link. But I don't understand
what is advantage of RSS offer to users. I mean I could NOT see the BBC NEWS feed content is updating that  is always same within several hours until I click refresh button so the content is changing

I thought RSS advantage for user updating news feed and its website content  to the most
update and without users click refresh button.

If we need to click the refresh button to update content , why we don't directly  go the exact
BBC news site to read the content  instead ?


The other question, how can I made my blog as feed. is it that I just go wordpress and
add RSS feed and change RSS link to my http://www.mywebsite.com/wp/ as I did for
BCC news feed. So other website if subscrible my blog feed  to get the most updated ?

So up to this mention, I could not find  the reason why people will use RSS feed, and
Any more RSS feed example demonstration to its advantage ?

Please advise

RSS is a specialized subset of XML.  You can learn more about RSS here:
http://cyber.law.harvard.edu/rss/rss.html

To publish an RSS feed, you simply write the XML file into a URL on your server.  Then you tell the world about the URL that contains the RSS.  

The way most of the world will access your RSS feed will be with an RSS reader.  An RSS reader is a specialized web browser that lives in your system tray and uses a timer to periodically start it's work.  Whenever its timer goes off, the RSS reader looks at all the RSS feed URLs that you have told it to follow.  It compares the existing information in its data set with the information it retrieves from the URL.  If the information at the URL has changed, it raises a notice to tell you there is new information at the URL.

If you want to republish an RSS feed, and you want to update the client web page with the latest information, you will need to read the RSS feed at page load time.  You might also consider having an AJAX timer-driven routine to re-read the RSS feed and refresh a <div> in the client's viewport.

personal i use an rss reader on my phone. it tells me when new postings have been made in my community and tells me about updates on various sites.

besides that i use rss for downloading in µTorrent.
there are sites i want to grab some things from automated and my µTorrent client rechecks in an interval if a new release has been published. if so, it starts downloading automated.
so in this way you are able to control applications with rss.

rss can also contain data and files. you could as example send images through rss feeds so if you would write a comic, all the subscribers would be able to read the new posted comics without the need to go to your site at all.

sadly most site owners use rss just to inform people about updates but do not put the updates into the rss. in this way the user is always forced to go to a link in order to see the whole update.
when reading through a small device this could become a pain then.



i hope this opened your understanding for rss. have a nice day.



PS:
anyways: i support nearly everything Bardobrave said.

he said he would reload a widget in an interval. that makes sense but if you are not using asp or php you could as example live send updates into the users browser (wich makes rss widgets obsolete)

rss should just be used to allow users to see stuff or updates from your site without going to your site.

Well... to the first question the answer is easy. Your page doesn't show the latest changes on BBC news because you are not reloading it. A RSS is the url to a site where news are compiled in a specific semantic way, that allow you to generate some coding to treat all news source in the same way.

You load the BBC RSS feed on your blog, so every time anyone arrives into your page he can see also the latest news from BBC (he saves one visit to BBC frontpage by visiting you, it's already worth of having it on your site). But, of course, if you do not say to your RSS widget to reload data, the BBC won't push it again to you.

I mean, RSS is a way to coordinate and simplify news recolection, but your system is who go and seek, not the feeders who send news directly to you.

However, you can program a timer to reload your widget (and not your whole page through AJAX) and get fresh news without making user to interactively reload page.

Also, people use RSS feeder programs where they process their different news sources, those programs go in a timely manner to the RSS urls stated on their preferences in search of fresh news, and retrieve them to the client, saving their users a lot of time and browsing.

Imagine you want to have news from BBC, EuropaPress, EFE, and two or three newspapers. You can insert all of them on your RSS Feed client and each 5, 10 or 15 minutes you'll have the fresh news from those sites without having to navigate them. This work in a very similar way to a email client (like outlook), where you define several mail accounts and the client retrieve received mail from those accounts and show it in your client window.

For the second question it really depends, I supose your blog should have an option for RSS, where it will give you a url, that url, if you follow it, will show you a XML code with info about your articles. Any user that want to follow your RSS only need to introduce that url into their RSS feed program, then, the program will seek timely for fresh news on your site and retrieve them directly.
