I've heard that lemon juice is esentially the same as yeast nutrition. Would there be any use adding a squezed lemon to the fermentor before pitching dry yeast? I assume it would be essential for a starter?
I don't know whether it's good for yeast but I'd guess that if it was added to the wort post boil it might be a source of infection. What about adding it with 10 minutes to go in the boil (just as you would with standard yeast nutrients)?
I use a teaspoon of old yeast in the boil when I remember, not sure I'd want to add the acid from a lemon, it might work in some styles, but not all.
Old yeast in the boil? Does the new yeast cannabalize the old? I would have thought the acidity of the yeast would make it ok to lob in. Then again I don't want to be the guy to ruin a brew with lemon juice.

Old yeast is one of the best sources of yeast nutrient apparently. I have some old dry bakers yeast I use.
Google says lemon juice is good for distillation but bad for wines, beer is not mentioned in the article I found.
I'd not use it myself as I think it'd end up in the flavour profile.
With some citrusy hops though...
