I think one of the most interesting things from my point of view was the importance of Peter MacDougall's plays. As a Greenockian there is an ambivalence about the success since while carrying a truth it's also worrisome that it in some ways it can be seen as glorifying it.
The old idea of treating the accent - or accents as only comedic add-ons went hand-in-hand with the virtual suppression of the Scots language as well.
I remember getting belted at primary school for not 'speaking properly' eleven months of the year, then being force fed Burns for a fortnight in January each yeaar, causing cultural confusion.
At least, with the resource known as 'the Kist', and a more enlightened attitude, Scots seems to be holding its' own - a thriving underground poetry scene, the trad music, and University studies at degree level, and now secomndary education qualifications in Scots literature are all helping.
Playwrights such as McDougal, Tony Roper and Liz Lockhead have been trail blazers.
Mind you, this year marked the 100th anniversary of Hamish Henderson's birth, and I think we owe him, and his 'School of Scottish Studies' a great debt.
