Internet development and anonymity (Score 1)

If you ask me anonymity is eroding as more people are using online products (emails, online chat, messengers, forums, personal website, blogs and etc.). How hard is it now to get a hold of your personal information by just your online ID and email address? Things like what you posted on certain forums, where you have been, your real name, your address, mobile phone numbers, a nice image of your house can be gathered by just knowing your ID sometimes. Of cause, you may very well argue that you aren't one of those who give up / disclose that much of information online, but my point is getting personal information has been increasingly easy. For example, with the integration of Hotmail and myspace, it's possible to know what a person talks on his/her blog by just knowing his email address. True story I found out some of my friends actually blog on myspace after I joined Windows Live Mail (by accidentally clicked the wrong button - "I'm willing to participate Live Mail Beta" - I know, that was stupid).
