I love Pinterest!
If you have a hobby you can find out more information about that hobby. There are people who post stuff of all different types from art, fashion, cooking, architecture, gardening, camping and survival, cars, trucks, guns, knives, stamps, coins, antiques ... just everything and anything.
Some of my favorite “boards” that people have are ones that show ingenious inventions or ways to solve common problems around the house, garden, camping etc. It is amazing the little tricks or “hacks” you can learn. At the same time it is maddening because a lot of them are so simple it’s like I COULD HAVE THOUGHT OF THAT!
It’s amazing what people are doing with old campers and motorhomes, I had no idea until an old GMC motorhome landed in my lap very cheaply, I started researching it, Pinterest started sending me suggestions with other peoples’ pinterest pages. Pretty elaborate stuff, not just full restorations but resto-mods like hot rod cars, all the latest tech built into custom retro designs.
