Hiogi Q&A Community

Hiogi is a pretty interesting service, basically a Q&A site based in Berlin that gives stuff that isn’t worth much to people who successfully answer submitted questions. Lot’s of growth and apparently a hot company right now.

Wish I could tell you more but the site is in english and all the Q&A is in German so I only got so far.

Facebook Suckage Syndrome

I guess Facebook really is just for college kids to poke themselves on. Oh well.

[From Scobleizer — Tech geek blogger » Blog Archive Facebook continues to suck «]

Yeah, pretty much. I don’t know anyone doing “serious stuff” on Facebook, and vampires and food fights are so last year. This is a real problem for Facebook and not only is it in their interests to do something about it, but they also have an obligation to all of the companies that are basing their future plans on Facebook becoming a true utility service. Robert may have a bone to pick with Facebook but that doesn’t make his comments any less valid.

As a nice contrast to my previous post about LinkedIn CPM rates, check out this data on Facebook CPM rates which more or less triangulates to other datapoints that suggest social ads just haven’t had the impact that proponents had hoped for. But hey, they are generating, apparently, an impressive revenue number and have plenty of cash in the bank so do have time to work it out.

There’s still a big opportunity here, but I will certainly admit that in my case aspirations got ahead of reality. In retrospect it is clear that many of the bullish Facebook commentators, like yours truly, were painting Facebook with expectations based on what we wanted to see as opposed to what they were capable of doing. Fair or not, Facebook still benefited from a huge push upward as a result of this, but the problem with leverage is that it works going down equally as well as on the upswing.

LinkedIn: We’re Selling Ads For $75 CPM

Yeah, I don’t doubt that LinkedIn is selling such a high CPM, but the problem for them is that I just don’t spend a lot of time in LinkedIn so the opportunity to lever up that CPM is limited. I’d bet that the average time spent when compared to other social networks is low, which means there is less ad inventory. This is something they should be concerned about because I’m right in their sweet spot for a target market and I rarely spend but more than 10 minutes a month in LinkedIn. How much you want to bet that LinkedIn acquires a social networking company in the next year?

Having said all that a $75 CPM is really impressive.

Since LinkedIn knows the professional histories of its users, and can target sales execs, c-level managers, or certain industries, we can imagine high ad rates for advertisers looking for a business niche. Still, we have a hard time believing this is an average CPM for LInkedIn. But we don’t have a hard time believing that LinkedIn’s average CPM crushes that of Facebook, MySpace and other social networks who routinely struggle to get CPMS above a buck.

Kalex Systems, Turning Waste Heat into Power

I met the CEO of a Kalex Systems recently, really neat guy with a fascinating company. The company’s technology is based on the Kalina Cycle, a method for recovering heat and converting it into mechanical power. I get excited about technologies like this because so much of the available energy at our disposal is thrown away as waste heat, everything from the exhaust your car produces to industrial processes.

What Kalex is doing is building small scale power plants that convert a variety of heat sources into power. For example, in China the company is building power plants that convert waste heat from cement factories into electricity. Concrete doesn’t dry, it cures as a result of a chemical reaction, and a major by product of that chemical reaction is heat. Up until now there hasn’t been an efficient method to capture heat, consolidate it, and convert it into power.

It’s often said that reducing our dependence on fossil fuels will come as a result of incremental innovations across a portfolio of solutions. Kalex is one such innovation that makes possible the development a wide range of industrial power plants, whether from the methane produced by a dairy farm (biomass) to waste heat (municipal waste) to geothermal.
