I've decided to stop doing it as I'm not really getting much or if it anymore - a sort of New Year's decision. I made it interesting for myself pretty much from the word go by never using the same word to start. I always used to use a word related to something that was going on that day either at home, the weather or in the news - something topical. I always started by using a word with only one vowel in it (and often the second word too) as I've always thought that it's really the consonants that help narrow down the possibilities so these are my final stats...
PS I also quit doing PlusWord - too many words keep cropping up time and again like opera or arena along with all those 3-2 phrases e.g.get in, get up, put up, put on, etc
