No use asking me what my starter word was. I've forgotten within minutes. I did it in four today, about three hours ago, and can remember neither my starter nor the answer. I'm as likely as not going to pick a random word from whatever I'm typing or reading at the time.

I might look at this post for a starter for tomorrow. The candidates could be "today" or "might" or "could" or "start" (a slight cheat there...) or "cheat." All good. But not "going" or "there." I think I quite often use the second line to try to eliminate double consonants such as TH, CH, SH, ST, TR, CR, PR, PL, BR, WH, that sort of thing, depending on what happened in line 1.

But look what I've just done. I've added "think," "often," and "thing" to my starter candidate list. But not "quite."
