How about highlighting especially bad practices by information providers about taxes? For instance if you hold Powershares etfs within Etrade, you might as well just shoot yourself.
Etrade: To find the percent distributions that are gov't sourced (maybe state tax deductible), you first find the name of the etf as a useless short abbreviation. OK, with much effort you translate the cusip. By the way, Etrade (unlike others) does not subtotal the distributions so you will have to add the dozen or so up, maybe without even the ability to cut and paste!
Powershares: To find the % number to apply to total distributions... as far as I can tell they have no such info (unlike others like ishares)! The only tax link seems to trigger a download (without warning) of a ridiculous .xls file which assumes you are on a microsoft platform with their spreadsheet software. If you move heaven and earth to unpack it on your platform, it appears to have no column on this issue.
