Dollar Tree being only a single dollar on everything.
I didn’t know Dollar Tree existed further back in the years like the 80s. But, I didn’t discover the store until like late 2000s. That store was a godsend for my then mostly broke ass. Sure the quality of products could’ve been better and the food selection could’ve been better, but they were there for me and others who’re strapped on budgets.
And it was a good 16 years while that lasted. It is a little annoying at times to shop there and know it is no different than Dollar General and Family Dollar. But it could’ve been worse.
StumbleUpon was what I personally cite as the peak of the internet.
It was a website where you made an account and selected what categories of things you were interested in. Then click the button and it would take you to a random piece of content on the internet related to that. I remember thinking at the time it was like Pandora, but for the whole internet rather than just music. Eventually it got bought and shut down.
Mint would be another one. A free, ad-deiven website with optional premoun features that allowed you to easily link all of your financial accounts. It would automatically categorize transactions, but you could manually change them and change the categories themselves. It worked great back in the early 2010’s. Then Intuit bought it and it slowly got shittier. They reduced the visualization options. Eventually a few years ago they shut it down to try to get people to move to a different, paid product. Personally I moved to HomeBank, an open-source self-hosted solution. But it means I need to manually import everything.
