We have had to pause development, but not only is your data still there, you can still use it. New users can't join, but that's about it.
As soon as we're able, we want to finish it and launch it. As part of this, we'll make sure people can get their data out in useful formats. (Perhaps a GeoRSS feed per URL? A KML file per user?)
I genuinely respect you for holding us to a high standard, but I think it's a little unfair to criticize us for an unfinished app.
