Some people (not me, you understand) might suggest that anyone who:
(a) knows what they are doing in IT, and
(b) has invested intellectual capital and some data in setting up services on a free web medium with no contractual obligations on either side, and
(c) who has *not* backed up their site/data

- needs their head examining.

Just as an aside note to my post, and for what it's worth: other studies in reading speed and comprehension identified that our brains can actually gain sense (comprehension) of what a printed sentence is saying even if we can only see the *top half* of a printed sentence; considerably less comprehension comes from only being able to see the lower half.

However, comprehension was much improved in both cases when the printed characters had serifs - i.e., as opposed to sans serif fonts.

The UK AA (Automobile Association) repeated this research post-war, and that was why UK road direction signs - maintained by the AA - were black on white or yellow, printed using serifed fonts. (I think the best was probably Times Roman.)

Serifed fonts not only enhance comprehension, but by so doing can also enhance our reading speed.

This would seem to be unpopular or "lost" knowledge nowadays, as we seem to prefer to use sans serif fonts that "look nice" - e.g., Arial, Helvetica, MS Sans Serif. It might seem idiotic to deliberately use printed fonts that can actually reduce our comprehension and reading speed, but, if we have massively irrational brains - as recent research would seem to indicate - then it's probably no surprise really.
