No we don't. I've taught RDF to a pretty significant number of people now, and I (now) start with a SPARQL database, with pre-written data in it.

Making triples visible is important though.

Perhaps - that's not really an argument in favour of is  of though, that's an argument for making it as simple to read/write as possible IMHO.

Reversing the direction of a triple is definitely an advanced requirement, and not likely to make Turtle easier for novices to read.

As an evidence point, look at the confusion around @rev in RDFa. e.g. http://stackoverflow.com/questions/9356293/in-rdfa-is-it-legal-to-use-the-rev-with-property

I don't think there's any difference in the utility. I handcraft about as much HTML as Turtle. My CV is maintained in HTML (with RDFa in it actually) for example.
