True that. Just wanted to get a quick feel from a few that's still 
keeping an eye on the mailing list and wanted to chime in. :)

Thanks for sharing! Nice use of latest.

If I understand you correctly, via slices, linking to individual 
observations is necessary, and one can still make their way to the whole 
dataset.

What I fear is dealing with insane number of slices and observations 
point from a dataset. I suppose caching or paginating are some ways to 
remedy the problem.

Aside: I couldn't get much out of 
http://environment.data.gov.uk/data/bathing-water-quality/LatestSampleSlice 
or http://environment.data.gov.uk/id/bathing-water/ukk1202-3600

FYI, I'm using the Ghostery add-on and it detects the Google+1 widget. 
Apparently, blocking that widget stops rest of the page to load. 
Everything else is okay otherwise.
