I find opens for this only really work if 1) they’re with someone who is going to reply because Nano, or 2) they’re an excellent poster. So not me basically :p I do agree with Bee that they’re more of a back-up option but I’d say that was true in general.

I wouldn’t worry about changing your posting style either. There’s a word count true, but for myself I’d be more likely to reply to a quality 200 post than a 600 one with lots of deep feelings but nothing to go off for a reply. That’s just me though! And shorter posts add up and lead to a much more enjoyable, less stressful Nano!
