Yep...that's the very site where most folks go off the common sense pathway. Try not to access that site for much if you can help it...she got the idea for fermenting on these two largest threads and then just added her own dialogue to it, but it has no basis in fact or is even advisable. The last person that listened to that on here had a big, glass jar explode all over their entryway because of that sage advice.
You can read on this thread and find links and information on just what constitutes LAB fermentation and none of it is concurrent with that information you have quoted. I know it's the site that first comes up when one does a Google on FF but it's not reliable or accurate in its information.
No, the extra water doesn't hurt anything...but you will be adding an extra step to your feeding by straining every time that you wouldn't need to do, then the soupy feed has been causing some to report runny stools, and the wetter the feed fed in the winter months, the more easily and quickly it freezes. It may not bother you now, but you'll likely be wanting a drier mix later on.
