Having a reputation online I think is harder to valudate and proctect because there are no history, non verbal cues and body language to count on. Which is why I think online dating is close to impossible. How can someone trust a profile base on just text or photo? These days any photos can easily be alter. I think there should be a dating sites where a potential mate should get other close friends and contact to build their website rather than themselves. This way a potential mate may find the profile more credible. The more people involved in the building the website the more creditble it becomes.
I question the fact how can all the profile say they are "funny, smart and intelligent" yet they are single? there must be a flaw in either their reputation or something else less to be desired. Therefore, it is always a good idea to google someone before getting too involved. However, as more companies establish their business to protect their online reputation (NPR) googleling someone may not work as effective as it use to be.
