I think that posting only to one's favourite games is quite normal; it's certainly my style, but it depends on how creative I'm feeling at the time, if at all. A good rule of thumb is that if you have nothing interesting, witty etc to add to a game then wait till something more promising turns up. There is increasing verbal incontinence and rule-bending simply for the sake of posting something. The whole thing is beginning to annoy me, and not just me, as I know privately. We could also do without those who post under more than one name, which is deceitful and sad. One has already been outed and I have a very beady pair of eyes on another one.
Trouble is, the limerick games are no longer and during the short bursts of time that I actually enter these portals, there's nothing else that takes my fancy. Apart from AVMA. Sometimes.
[CdM] Maybe a long verse game? Although admittedly the last few attempts at "hard poetry" didn't seem to attract very many of the current Mornipersons.
