I think I totally do the unicorn thing. Many years ago I got into what I discovered was linked data and the semantic web. I was psyched to build what I called a distributed economy. Sooner or later I found myself on the W3C lists working with people from around the world that I found were a lot better than me.
I got to know a guy named Manu Sporny who is psyched about linked data and making payment systems interoperable (if I understand correctly). I got approached by a number in the Bitcoin community, but I ended up working more with simple linked data (and not how they might interoperate though things like Bitmark).
Later I got involved with a startup wanting to put linked data into their Drupal site. I obliged. We were dissapointed that we did not get further sooner. I met a lot of cool people in Boston, Austin, and San Francisco. It was definitely worth the trip.
As I learned more about the linked data and the semantic web I heard about this guy named Tim Berners-Lee. I told someone I wanted him to respond to my e-mail (but I knew I had no reason at the time). Later I talked to him on gitter and a whole lot of other people around him. It seemed pretty cool where this was headed. A thing I struggled with really is this stuff was hard.
It was difficult getting something running that wowed the non-domain user. So...I have to discipline myself daily to get down and tear something apart. It helps also with the weeblies of being around people a lot better than me.
From experience, it seems really hard getting jobs in this area. A lot have 8 yrs of experience, are intermediate developers, and maybe have a PhD. But I did hear from a head hunter at least recently. This was a prickly pear in the desert. It also has been exciting when people from faraway places want to connect on social media. But then there is this thing called money. It is not understood.
The chase is too much fun, and I'm oddly influenced by hackers who leave me in a trance. But I feel better maybe because I'm sweating doing things that may actually be semantic web. Maybe I'll push that one thing out that will enable a plethora of possibility.

Abstract: An advanced model for melt blowing was used to predict the effects of modified air fields on fiber formation. The model, which was developed previously, involves the simultaneous solution of the momentum, energy, and continuity equations. Crystallization effects were included. The model equations were solved numerically. Simulations were done for two classes of modified air fields. The first class of modified air field has a plateau of constant velocity and temperature. For wide plateaus placed near the die face, the effect of the plateau is substantial. Fiber diameters are reduced (by up to two times) versus diameters for when there is no plateau. The second class of modified air field has a quench (or a plateau-quench). Quenching was simulated as a step drop in air temperature. The simulation showed that quenching can enhance online crystallinity, though fiber attenuation is reduced when quenching is used.Next-Generation Modelling of Melt Blowing -- Ind. Eng. Chem.

Abstract: An advanced model has been developed for predicting the behavior of a fiber as it is formed in the melt blowing process. The model involves the simultaneous solution of the momentum, energy, and continuity equations. Crystallization effects are included. The model equations are solved numerically. As a bottom boundary condition in this solution, a stop point is assumed. The stop point is the point where (a) the fiber stress is zero, and (b) the air velocity and fiber velocity are equal. Predicted parameters include fiber diameter, velocity, temperature, stress, and crystallinity. The predicted results show that very little online crystallization takes place under typical melt blowing conditions.On-line Measurement of Fiber Motion During Melt-Blowing -- Ind. Eng. Chem. Res. -- Publication Date: Oct 3, 2007
Abstract: A high-speed camera was used to record the motion of a fiber below both a melt-blowing slot die and a melt-blowing swirl die. These recorded images were processed to determine the frequency and amplitude of fiber motion during melt blowing. The operating variables investigated included polymer flow rate, air flow rate, polymer temperature, and air temperature. A crossover counting method was developed to determine the frequency of fiber motion. The frequencies determined from this counting method favorably compared with frequencies determined by taking fast Fourier transforms of the fiber displacement data. Experimental results for frequency and amplitude were compared to predictions from a three-dimensional mathematical model for the melt-blowing process.Chemical Engineering Undergraduate School:
