It will depend on the weather and your watering. Here, given the consistent heat, mine is almost always bitter and never grows all that much. One year that I can recall it was ok, not great but ok, but I prefer to use the space for something better and more productive.

I have had a baby romaine re-grow regularly and be very edible, It is going to depend on how hot it is there, mine is pretty much in the shade, and in WI instead of Ark.

So for you reseeders... what do you do? Just leave the plant and let it grow high and reseed? I have my lettuces and spinach now that have bolted (they've grown vertically with high stem) and the spinach has flowers on them. what should I do at this point to get a fall crop out of them?

yes - leave until seeds mature. Then collect or let them disperse. It takes longer than you think for them to mature, so don't cut them until you have found mature seeds.
