I keep a track of website hits over a period and hits dropped off dramatically when I had the video up.
your statements doesnt make sense to me (pray i will not speculate). why every time you put advertisement materials such as manual/guide, videos, screenshots/examples the hit dropped is a 8th wonder of the world to me. and time spent to keep track hit counter better spent on improving the SW further. just publish the materials and forget about it, let the audiences decide to hit buy now button or not. or are you saying those introductory materials will jeopardize your sale? by removing them you will increase hit and sale?
anyway kudos for your effort in making the video but 2 resistors circuit is hardly practical.
talking about competitors... few years back, i've attempted to make an eda designer, i called it Chromeera Project. took half a year to code just few data structures/gui etc, that was really heavy and difficult task, and i may say, wasteful as it occupied and took me away from other ee hobby /part time stuffs. thinking i only moved very little in half a year, and my VB6 IDE is rotting so not worth the effort, i decided to stop until i have better modern IDE proficiency (Qt was choosen) and time allocation for it. attached is what have completed so far (still on half breed GUI development, zero functionality) if only i can clone myself into 2 or 5 other persons, i'll command one of them to spend entire life on this task. but joke aside, no i dont want to compete with you, i only hope some day some people will come up with better and modern EDA yet affordable, this EDA will include EM solver, RF, integrated SPICE simulator, differential/length match/impedance control interactive bus routing, MCU/FPGA embedded C/C++/VHDL built in and simulator/debugger everything that a modern electronics design will require, fwiw...
