I've said this many times, the aim of the blog has never been as a teaching/educational channel.
And as for more FF videos, yes they will come as the mood takes me, but as I've said before:
a) They don't get the same reception or views as my other more general interest videos
b) And a good proportion of feedback on any FF video is people asking "can you do xxxxxxx", i.e. no feedback on the current one I just did, as it seems people like the concept but aren't entirely happy unless I do the exact topic they want.
