Chris Nolan talked to us today and he spoke about the credibility o Web Pages. The largest search engine is Google, followed up by Yahoo. When we search something in the Internet, the results that appear first are there not by casuality but because they have been linked the most times with your search, and thsy have been what people are most likely looking for in previous searches over the same topic. Google gets all their money through the advertisements that appears in their Web Pages.
What I learned today that I thought was pretty cool was the idea that you can limit your search in the Advanced Search tab, this helps you find information that is actually usefull to you. Also Google Scholar is a great tool to use because it gives you academic information.
What I found really surprising was what JCPenny did to get to appear in the first positions of any type of search.
It was a cool lecture and also a helpful one!

Reasons to Hate PowerPoint
PowerPoint is a Microsoft Office program that allows people to gather information related to one topic as well as it allows the person to exhibit or present this information to the public through a conference, a class, or a lecture. PowerPoint lets you do so many different things that, if put all together, it may seem overwhelming, unattractive, and most importantly boring.
In the following I will express some of the aspects I dislike about PowerPoint presentations.
To begin with, I cannot stand when people load their slides with text and just read what they have written. If this is the case, I consider the speaker unnecessary because everyone in the audience can read what is on the screen (and that is only possible, if the information is visible).
Another thing I dislike about presentations is the sound effects that are sometimes included in the slideshow, I think they are extra and distracting. Besides, when I had to learn how to insert sound to presentations, I had a very difficult time.
Also I think that some transition effects that PowerPoint offers to change slides or to present text or an image, are sometimes to slow and this makes the viewer lose interest. I hate the effect that put one letter at a time, it takes forever to finish.
I do not like when people use bullet points and do not make themselves clear. It is good to shorten the amount of information, but that should not mean that the points they are expressing should be unclear and incomplete.
When presentations are very long, I get frustrated and lose concentration, I get tired of looking at the presentation. In one of my classes, I have to sit and take a lecture based on a PowerPoint presentation that is 55 slides long, and worse of all I have to study from it for my tests (I do not appreciate that system). In contrast, I also hate when the speaker goes on for a long time but has very few slides to present and get hooked in one for a long period of time.
One very annoying thing is when you can't even see what is on the screen because the font is very small.
One of the most boring PowerPoint presentations I have had to sit through was an Art History one where there were only like four pictures and the speaker kept talking about the same picture nonstop, there was no background, no text, no nothing. I wanted to fall asleep!!
