The viewers and purchasers from QVC and other shopping channels could be down. Makeup is sometimes an impulse purchase and you don't want to wait 2 weeks for it to ship to you and pay extra for that shipping.
Colors are deceiving on the TV and on a monitor. It's expensive and disconcerting to receive a foundation or lipstick that you thought would match and it's totally off. If at a store, you can swatch it.
My other explanation for the lower number of threads here is the average age of those on these forums. Most are retired, don't wear as much makeup, after so many years have settled on a skincare routine and/or not spending as much money trying new cosmetics.
I enjoy starting a thread or checking in and posting a reply, but you're right that many days, there's nothing new. Sometimes the same questions are asked that have been answered many times here before and I skip over those threads.
Until Q changes and includes some new, exciting beauty lines, the Beauty Forum may not be as exciting as it was before.
