NEARLY 15% of my spam-cleaned mail comes from people who find an interesting tidbit online somewhere so they send it to me (and normally a bunch of others) to read. Many times I just get a link and no context. Since I get most of my mail on my phone, I won't follow the link to ad-heavy news sites. If friends want me to share their eureka moments, they should blog about them. It's highly unlikely I will wander off and blindly follow a hyperlink, no matter who shares it with me.
