IMHO there is acute lack of interesting data sets for statistical education purposes, particularly cross-sectional in nature and not related to biology/medicine/astronomy. The domains I am looking for are management, demography and economics but sport is OK too as many students are interested in sport.
I agree there is a lot of data published (mainly) by various government agencies but its almost 100% time series data. There are many test datasets too (like UC Irvine Machine Learning Repository), but they are usually boring, often categorical and short:-)
To remedy a little the lack of good data I compiled myself a few databases and I intend to add more in the future. At present my repository consists of 4 datasets concerning: -- 1100 or so German WW2 U-boots; -- 2200 or so Titanic passangers/crew members -- 1200 or so Rugby Union players who took part in RWC 2011 and RWC 2007 tournaments.
The repository is available at my github account.
Aż wstyd, że dopiero dziś się dowiedziałem.
24. października br. zmarł John McCarthy, twórca języka LISP (1958 r.), drugiego po Fortranie języka wysokiego poziomu powszechnie używanego do dziś. Ja też -- nie chwaląc się -- czasami go używam, choć go prawie nie znam:

count words in buffer"
