What the hell is AGGREGATOR / READER?
OLÉ I do not read, I read READER!
Most of the people around us in civilization read newspapers in particular (although there are others who do not read anything), such as general news daily with " Clarin "," The Nation "or something more timely and athletics " Olé "(Newspapers in Argentinas), another sport is Playboy (they say they talk about games like melee, only practiced by women, although men who have no other sport is more manual literature)
In general news publications as you read on average?, I of a journal of 100 pages, at most 2 full pages, therefore 98% of the newspaper does not interest me (and if we speak of the waste of paper ...), my friends mostly read sports publications such as "Ole," but I do not (although I like sports in general, do not practice now and I have no interest in reading something related).
What I really like is obvious: "Technology in general", the issue is there is no daily publications with information on technology 
.
And this applies to specific issues, there is no paper publications of these issues, such as: Cooking, Theatre, Series / TV, Boliches gays (for many of my friends Cordobé, Dino, Nacho, The Chinaman, and many more) , etc.
As I can do to be informed of specific issues?
As commented in the post above about RSS, it's time to use it, the magic formula:
BLOGS / SITES + RSS + AGGREGATOR = "Personalized Journal."
The concept is thus: On the one hand we have the source of information, be it a blog, site, or X source, these sources must publish their content in RSS format / ATOM, then a AGGREGATOR see the content, the flow would be something like:
BLOGS: Besides counting on the personal life of a monkey in particular (that's the main objective), they also serve to transmit information, where many blogs are focused on something particular. It really is having increasingly important blogs even on traditional media, for example, a network of blogs that is valued at 4.5 million.
In legacy mode to be interested in a few sources, one should go manually for each of these and see if there is new content since the last time we went, this besides being slow, cumbersome and terribly especially a BIG loss time.
Almost by definition blogs have RSS enabled mode, this allows us to use an aggregator to read its contents, without having to "pass" for the site.
Basically: The source RSS-enabled mode, each time you create a story / post automatically generates an RSS feed item with the site in the FEED (add an item to the list of RSS), then from a aggregator you "low" that item to read. So, instead of fetching the content, it comes.
The action of adding a source to a aggregator is known as subscription.
TUTORIAL: READER
Reader is one of the best known, being of google and its simplicity of use. (Explain what applies to "reader", but the concepts are the same using any other aggregator).
First we must activate the service Reader (not sure if it's for google accounts (allowing them to be in another domain) or gmail accounts directly)
There are several ways to add feeds from one site to our Reader:
The fastest is: Within the site in question, look for an icon like this: 
(Many sites / services consumed feed usually have a sign "more" representing an Aggregator)
In our case ElTecnoloco.com have a collection of icons for various aggregators (by relying on "subscribe" displays the list), and click on "Google"
Then we ask: Where it says? to igoogle (google's home) or the reader?, to which we respond to reader:
Once we add to the reader, let's see what we are left subscriptions, and to the right the contents of your subscription, adding it to end is going to appear without reading the latest blog post, simply "escroleando" ( down the scrollbar), we will begin to discount the unread.
Another way of subscription, is knowing in advance the list (feed), is often, called "domino / feed" ElTecnoloco is http://eltecnoloco.com/feed, this was added through the "Add subscription" ( left)
Well that's all folks!, Was longer than I expected: S, I hope they have served and have added to their readers ElTecnoloco! 
Soon will continue with more benefits of the reader and other things interesting, see you soon and remember that comment does not bite!
