I came across an interesting project that had the same idea as dripread at
Unfortunately it barley seems to have gotten off the ground, but it did give me the idea of making Open University lectures available on dripread.
In fact I think the dripread delivery mechanism of a bite size chunk off information in daily intervals is a good way to learn about a topic without having to make a concious effort to site down and study.
If it makes the difference between a student actually reading the material and them just meaning to read the material but not getting round to it, then dripreading would seems worthwhile.
Anyway, here's a first version of a short course I have adapted on Evolution via dripread.
Let me know what you think
