The spammers don't care about your readers. They only care about the googlebot. This is one form of SEO.

Ironically, it doesn't work. Google got wise to it a long time ago, and now it actually reduces their page-rank. But the SEO-service companies don't tell their customers that, for obvious reasons.

Sadly no. Of course I get a little bit of that on occasion, but it would not merit comment. I any event, being so close to graduation, I keep the mask firmly fitted while on campus.
No, this warrented comment because these are people I've known for years.
6 months ago my twitter feed began filling up with bile. The culprit was a fellow I've known for 24 years, who is a bit of a hippy but has always been an interesting fellow and a very decent guy. He was someone that In a lot of ways I'd admired because he'd overcome some serious obstacles to raise a family and pursue an education. I hadn't heard from him except in short tweets and E-mail exchanges for about two years. 
The bile in question was rage aimed at MSNBC for firing Martin Bashir as my friend was of the opinion that what Bashir said , that Sarah Palin should be tied down and have someone crap in her mouth, was quite reasonable. Now I am not a fan of the school of thought that saying anything that offends someone is a hate crime...but there are points at which one is no longer engaged in reasoned discourse, and that seems to  not qualify as such.  My friend felt that she should be raped as well and linked approvingly to a Dan Savage piece that suggested that she have nails driven into her during the process so that her screaming in agony would prevent her from closing her mouth . I pointed out that my friend had a daughter, and surely he did not want her to grow up in a world where talking about a woman that way was acceptable. He responded that his daughter was a progressive and so this was not about her and I was a fool and a misogynist for suggesting that it was. I asked if he'd still love his daughter if she came home from college a Tea Partier. He said no he wouldn't...he'd disown her. I made some clumsy analogy to the tragedy of homophobic parents cutting off their gay children and the conversation deteriorated from there cumulating in a multi question quiz, which I failed.
A few weeks ago I was asked to sign a petition by someone I've been on friendly terms with for over 15 years, though like the other one I hadn't seen him IRL in a couple of years. I did not sign the petition which I considered well intentioned but flawed. The fellow was floored and hurt. When I explained my concern he expressed his deep and profound disappointment at discovering I had a diverging opinion....all messages from the mailing list we were both members of stopped shortly thereafter.
I could go on, but won't, the point is that over the last 6 months 3, possibly 4 people I've known for over a decade have decided to do an assessment of my views, found me wanting and cut me off lest they be associated with me. 


It used to be possible to have friends with wildly different worldviews, but we are becoming so polarized that society is breaking up in an almost tribal fashion. Said tribes don't associate and membership in the tribes is determined by questions that are graded digitally.
How I long for the days of analog.

Even more than the current fusillade of scandals and the stuff happening overseas, this dynamic worries and saddens me. 

In the 50 + years I have been on this earth one word to the wise I recieved early on and stuck with me was that in this life one has in truth only a few "True" friends. Most can be counted on your fingers. All the others you cross paths with in live are really just acquaintances.
