Not trying to sound flippant, CharlesCS: Why not wear a mask which would allow you to enjoy the ocean which is much easier and safer "to dive into". Just as you take precautions on the Internet, precautions can be taken when going to the beach... For instance, the probability of sunburn vs. sharks and jellyfish and using sunscreen. Not making fun of your fears. I'd never do that. Just suggesting a solution which might make more enjoyable options for you, my friend.
No problem with that. I'm not afraid to admit my fears. I'm afraid of cemetery too. Sure, I could use a mask but that will only allow me to see that which I am already afraid of. I avoid the ocean because I can't see the possible sharks down there, the mask will only scare me more. LOL. But as CarGuy said, not every ocean is clear. But even if, I still don't like it. Don't get me wrong, it's beautiful down there, I have used masks before to see the small fish and the coral reefs but I still don't like being down there too often. By the same token I would avoid the African plains and the jungles of Brazil.
Google+ Invitations Likely Spam I am sure the same people will get caught out with this...
Keep in mind you control what you see on your stream and who sees what you post. If spammers wanted to get your email they would get it regardless if your account was private considering you're likely to use it to sign in on different sites. Even Joeuser gets cluttered with spammers on weekends, it's inevitable since, for now, it's part of the Internet whether we want it or not.
Stardock's customers/site members' details/information is confidential. No-one's email address [for example] is communicated to anyone without their consent. Privacy Legislation requires me, for example to be at a somewhat unique User Level to prevent my access to Users' banking details [because I am outside the US], yet other info is accessible as site Administrator. Obviously, commercial practice requires legitimate email accounts, etc for the handling of product sales, but the majority of User names, etc. are pretty obviously fabricated.... Apart from here [obviously], I have online info/accounts with the likes of Amazon.US and Amazon.UK and likewise see the logic and benefits of such. I cannot, however see how letting a Search Engine intent on marketting my 'Interests' to all and sundry can be a plus - to me. It's sole benefit is to be a 'plus' to Google AND their Advertising customers.
I know they are confidential but then so was the info on the Sony site and the many others who got hacked. Not to mention one can use the email (as an option) to log in and some people just are not always careful with this info in public places.
BTW, I was just looking at my profile and I noticed my gender option was blank. When I went to change that I noticed several interesting options in there. Very interesting set of options. LOL.
