There are currently 9 questions tagged ipad. Unless it was really the only product of its kind, why not use the umbrella term instead? In this case, tablet or, if you prefer, tablet-computer. While ipad is easily understandable, it still feels unnecessary for us to promote a product.
Not that it has any impact, but it's more about the principle, and about remaining neutral, if possible.
The one other case I noticed is pediasure (child nutrition). There are two questions:
Is PediaSure okay for toddlers and if not how to get them off it?
This one directly concerns PediaSure.
What are some good food options for a one year-old?
I'm not sure why this got that tag, though (they actually mention two other brands in their question). So that tag could be removed.
Then, only one question remains - one tag for one question may not be necessary.
My question is
Shall we try to remain as neutral as possible with regards to tags?
(this doesn't exclude the possibility that such a brand-/product-tag may be useful.)
