Google Chrome is a new web browser built by people who know web services, web software, web ads, web… well, you get the picture. Why did they build yet another browser? Because in my opinion, it needed to be done. Instead of one big program that holds all the web pages, you get lots of little programs, one for each tab. The browser they build becomes essentially a manager of lots of little browsers. Why is this a good thing? Because sometimes

bad things happen when you load a web page containing say the latest mega-monster-video-game. Instead of all your tabs going away, just the one that was being bad goes away.

This might not seem like a great thing but I think it is. As a software developer and programmer of web sites, it means that the web pages I create will work better, work faster, and just plain work. I won’t get calls any more because something went wrong while someone was in the middle of using my website.

So what is this part about Big Brother you say? It has to do with the EULA. That is an acronym for End User License Agreement. When you install this great piece of software on your computer and use it, Google says they own every piece of data you look at. Everything you enter on a form. Everything you surf to is theirs. Don’t believe me? Take a look at some of the news out there. This article has a copy of the text from the EULA itself. Here’s another article, and another. If you want to see the EULA your self, then here is the location.

It is stuff like this that really gets me fuming. They come out with a great tool, but then have to mess it up with legal garbage like this. Hopefully this will get sorted out and the offending clauses get fixed. Until then though, I won’t be using this great tool.
