A blog is a personal internet diary that other people can view, comment on, and communicate with you on. Many people use it to ask questions, find help or share their views and opinions with a large group. The other day i was researching on the internet to find out peoples opinions of primerica, because i had been recruited by someone in it.
I think this is a good example of how opinions fly and internet arguments are fought. I still haven't decided whether to take primerica seriously yet, but this was an interesting blog i thought. I also looked Primerica up on wikipedia, as well as rip-off report, and found fairly positive articles. I will look into it more.
Web 2.0 lets the masses become the authority on the web, by allowing normal people to influence, and update, and change the available knowledge out there. In blogging, people can voice concerns, and the world gives you an answer. It is quite an amazing change, that has really only taken place in the past few years. It is very important, and will begin to affect all of us more and more as time goes on.
