I think you are on the right track my friend. But I will prefer you stick to video learning as blog and written tutorials can be too difficult to follow up with.

What about combining both video blogging and the traditional blogging? I this would be alot more effective as most times the videos might be too fast to follow up but when written you can also read it for a better explanation. Or what do you think?I prefer the vlog tutorial because nowadays it is easier and more convenient for you to watch a video than to sit and read something. it's just my opinion.
