2)What percentage of the fonts that you download do you end up using?
Close 5% (but 100% of my installed fonts)
It's necessary to have a spool of a good number of fonts with a large variety of styles, to have a choice when you need one.
But I download only 10% or 20% of the fonts I look (for exemple on DaFont). I select only the font a "can" want to use anytime.
I use them in GIMP for graphics

websites, flyers, newsletters, logos, texts,... basic use of fonts.
i only download what i need, when i need it.
I'm not colllecting fonts.
