Google Latitude
Google has many problems with privacy. The first being that most people do not want their personal information shared with people that they do not know. This kind of information could be used by stalkers and other evil people to do things that are bad. I personally do not want someone to know where I am at all times. I realise that i would be giving the information freely, but i think that some kind or privacy is needed.
Facebook is only a problem if the person is stupid and dosn’t block people that they do not know from looking at their profile. their information is completely safe if they simply do not let anyone but their friends look at it. This also applies for pictures. If you block people that you don’t want to see your stuff then they will not see it.
I belive that this is a good way to find potenitial people because there are going to be alot more people to hire online. They can ask for a meeting with the person so that they can see if they are actually the person that they say that they are.
