The more you talk about suicide, the more people commit it. It's a terrible conundrum in spreading awareness of how many people actually commit suicide. If there is a high-profile case of suicide reported, there will usually be an uptick in suicide and single car, single-passenger car crashes by people in similar demographics. There is an entire section in Cialdini's book Influence, on the social proof of suicide, and I just recently heard this Freakonomics podcast on the subject http://www.freakonomics.com/2011/08/31/new-freakonomics-radi...
Tumblr isn't a bot fest necessarily, but the fact is that any site with a large amount of traffic will generally become a target for bots. It's almost a compliment to a website, but at the same time it can be a nuisance. The Tumblr bots I'm familiar with follow by category and tags, not necessarily post content. The reason the author's blog gets autofollowed is likely because he is in a lucrative niche.
Captchas won't really stop them, it just adds expense and time. Many black hat tools integrate captcha breaking services. Cost is somewhere around $2 per 1000.
I drove the Karma last month and it was pretty awesome. I'm big on electric cars, but the downfall of 100% electric is a term called Range Anxiety. Which as the name implies, is being anxious about how far you can go. A car like the karma has a gas tank that allows it to go up to 250 miles more after the 50 miles of battery are up. That is the main difference I learned between the electric vs hybrid cars, and to me an important distinction...
I absolutely agree about Range Anxiety if you have only one car, but if you've got a nice gas-powered Audi now, and a diesel F-350 work truck, it's pretty reasonable to get a pure-electric car to leave at the office for daily trips, and maybe to use for commuting. There's no practical way to drive more than 300 miles in the Bay Area per day (unless you just drive it around in circles); I rarely do more than 200.
I'd think of it as a 2-3 car setup. The truck is shared at my company, and my gf doesn't have a car of her own yet, so having two personal cars would be reasonable.
But what I really mean is that no one is likely to be happy with JUST a battery electric vehicle; they will want access to a refuelable car for longer trips. And, personally, I don't want to put 1500 mile trips on an $80k new car; I'd rather keep my NPV $12k 2006 audi for that kind of thing, and keep the miles on that.
For a daily driver around the bay area, though, the model s looks perfect.
Another decent way which wasn't mentioned here so far is to comment on other blogs and pages with similar content. Not only is it a boost for SEO but, if your app is related to the post, people who read the comments will click through if relevant.
In SEO a main strategy is actually doing this, blackhatters use software that automatically posts comments on related blogs, but the whitehat (clean) method is to do it manually, and it works. Try to comment on as many high quality blogs as possible (high Page Rank).
Tip: Try to use your keyword for your name so it is anchor text, although some blogs might not approve your comment because of that.
The area that Groupon really shines in, and that Google was trying to acquire, is the vast number of local salespeople on the ground. Customer service and interaction are not Facebook's strong points.
