Following my comparisons between OpenOffice.org Calc, KSpread, and Gnumeric I got to wondering what spreadsheets are the most popular for all you other GNU/Linux users. I started a poll that you can find here. Promote your favorite and vote.
Options include OpenOffice.org Calc, KSpread, Gnumeric, Excel through Wine/Crossover/Virtual Machine, PlanMaker, FlyCalc, Google Spreadsheet, Oleo, and SC. Of course you can also vote for Other and write-in your choice.
