I think it should stay "together" as it is handy in so many ways. It may cause a few arguments along the way but an argument is just a tool to decide right from wrong and bad from good etc. There are people on here who are new to window cleaning and it is helpful to them to look at both worlds e.g trad and wfp.
If your in just one section, then it is fairly likely there will be less information to spark you off into "wondering" about what others are up to and the possibility of gaining an interest in there field of work.
When i came on here I didnt even know how wfp systems worked, but luckily there were ppl on here that talked about there wfp work and i had to find out from them what it was all about. I may or may not go into wfp, but still...the advice and experiance was there and now i have an understanding of it. Im not saying i couldnt have looked elsewhere for the info but it was still worth learning about!
at the end of the day, this is a very good forum and i have learnt a lot from the ppl on here and i'm sure others have too, arguing is common place when there are two different types of job within the same ballgame (if you know what i mean) but that does not mean its a bad thing...just real life!!
