Add your view on the lithology/geology, because this is purely based on some amateuristic observations during my holidays and not by decent fieldwork or literature review.
I'm not going to do it yet, but I'm suggesting removing the geological data. It's of interest, but it really belongs in the wikipedia Sifnos page rather than on the travel page. Maybe the contributor could move it there. I'll delete it eventually unless discussion justifies leaving it. Sailsetter 18:44, 8 March 2008 (EST)
I've removed the geological data. Sailsetter 10:20, 11 March 2008 (EDT)
I've removed the first line of the article, since of the three things it contains one, the island name, is already in the lines immediately above and below it, another, a link to the Cyclades section, is already in the line below it, and the third is a link to a hotel aggregator site which we're not supposed to do.

Add some antiquities sites. Sailsetter 19:04, 26 March 2008 (EDT)
I think this article qualifies as usable, though it could use perhaps a couple more hotels. But most other information is at least usable quality if not more, so I've changed the status to usable. Sailsetter 15:32, 7 April 2008 (EDT)
