ArcView 3.x is alive and kicking
GIS Lounge have a nice article entitled Why ArcView 3.x is Still in Use. And the funny thing is that it describes (by inference) all the problems with AV3 and then goes on to say why it can still be better than ArcMap. Not really a glowing recommendation for ESRI. And yes, incredibly poor performance, high overheads of implementation, draconian licensing and the arse-about-face way of doing things. Yup, it is usually quicker to do things in ArcView 3.x (create a new shapefile, delete vertices etc etc).

A better way...
The Free Our Data Campaign report on the Show Us a Better Way "competition" from the e Power of Information Taskforce. In short, getting people to come up with good ideas for the use of public data. What's nice that they have a brief list of data available and have posted new datasets. Makes for interesting reading even if you don't post any ideas!

Geomorphological definitions
I came across a recent USGS publication today, Annotated Definitions of Selected Geomorphic Terms and Related Terms of Hydrology, Sedimentology, Soil Science and Ecology. This is a geomorphologically focussed "dictionary", although there is a bias towards fluvial environments. Possibly not as useful as the Penguin Dictionary of Physical Geography but none-the-less well worth a look at and with a more inter-disciplinary focus.
