Marden gave some excellent suggestions here with he video series he referenced. I have seen the same type of "How-To" videos on just about every type of platform, language, software that I have used. It makes it very easy for the novice user to know what parameters can be adjusted, the proper syntax to use, and where to put the code to make things work.
The type of thing you assisted me with earlier today, "lookup functionality" - and easy solution, but if you don't know where to find the proper parameter to alter, and what to write in the box, it seems very daunting.
I think you have a great product here, but I think it will grow exponentially when you give your users something to think about, and some good instruction on how to do - whatever they need to do.
Currently, the only a very few of the videos you have posted have a voice to explain what is being done, and the ones that do go so fast you couldn't possibly keep up if you wanted to. The others are only music, and again, the quality is so low that you really cannot see the very tiny mouse zipping from place to place very quickly - and you cannot learn or understand what is going on.
I'm not complaining - your product is amazing, but I think many people will benefit from instructional videos that cover some very basic - and even some very advanced techniques - so that the user can see what is possible, and how to do it.
Just my 2 cents.
