lately i've let a number of threads develop for a few pages before opening it, then read the first post and then go to the end of the thread and follow it backwards. it's really interesting to see how discussions evolve (or devolve) sometimes. it's very different than participating in a thread from the get go and being in the mix as it develops.
We don't know what our limits are, so to start something with the idea of being limited actually ends up limiting us.
