@Murta, I agree, some basic assignments should probably be in the chart - it was already getting a little large although better design would free up some space. Actually another follow-up cheatsheet with assignments/manipulations involving deeper datasets, use of (presumably upcoming) Replace, ReplaceAt etc usage, other aggregation operators and especially GroupBy would be useful. I’m assuming these assignments, and efficient memory management issues will be resolved in upcoming months but IMO of interest will be the ability to refine/test a wider range of algorithms on an “industrial scale”.

Yes, datasets for which analysis is made possible or easier using WL capabilities.

comment Historical Exchange Rates via FinancialData
The motivation of accessing this data comes from several recent hunches that the Australian dollar is significantly overvalued (anticipating a fall to ~80c by 2015 for future hunch-judgers) but don't particularly trust my intuition when it comes to predicting notorious currency movements - nor for that matter Australia's Reserve Bank or this country's economists. Whether big data-driven finance models can prove to be any less Sisyphean, Faustian or even King-Cnut-like is debatable but going there would at least appear inadvisable without access to such historical data.

The range of computational data available in Mathematica promises much but not making explicit current scope limitations is IMO unfortunate. Part of the power of the Wolfram Language lies in its generality and uniformity so it's a reasonable expectation that unless notified otherwise this will extend to data sources. Where it does not, either because curation is not yet possible or else subject to further licensing, making these explicit (perhaps graphically and/or through additional licensing instructions) would greatly assist users scoping out potential applications.
