Dangers of Blogger

1. Search Engines list you - What you publish may be read by people you don't wish to have contact with because search engines like Google, Yahoo, MSN and Bing will list your blog according to keywords. 
2. Your content is public - What you post, for example, photos can be viewed by not just you but EVERYONE on the internet, so post with caution. ^_^
3. You don't know who views your content - Stalkers/ perverts/ pedophiles who view your blog do not leave any trace of a visit, so be sure to secure your content as much as possible, if not, information that's private might be known by people you don't know.
