Idea: having a post filter that searches for common Tetris related acronyms (DAS, TDS, TAP, Ti, TGM, ARE, B2B, TST etc...) and adds an <accronym> tag (or <abbr>) with the proper title attribute around it. So for instance, HTML: Guidelines games such as TDS definitely need a fast DAS. becomes HTML: Guidelines games such as <accronym title="Tetris DS">TDS</accronym> definitely need a fast <accronym title="accronym for Delayed Auto Shift, i.d. autorepeat">DAS</accronym>.
but not something that has a single "proper title". Though of course you could easily just assign it one (entry delay).
