some users make the same password for their email and facebook account,so it is easy to hackers to go to the facebook account and change their data and access,they should mention that the password must be different and contain alphanumeric characters and even symbols to avoid such fraud
I get to keep up with people I rarely talk to, and can connect to people around the world with interests similar to mine. An excellent site if used wisely, avoiding the applications that are nothing more than information harvesters.
The site has recently messed up their Privacy Policy, saying thay have the master rights of everything you post on their - your photos, writing, profile etc.
Users can upload bad content, such as inappropriate images.
It is slightly safer than some sites as your content is not made public by default.
Its a networking site, most people will know/see what you do/done/will-do in your life....privacy is not that big here, but then again you are the one to fill the info for others to see. So be aware of what you post.
Its fun and good site to use for sharing and meeting new people however like all social networks there is always security and age related issues, something you do at your own risk but overall its all good.
