One success story is of a woman who sold her old vinyl records collection at a car boot sale. She had been storing them for years. She priced them fairly and attracted a music collector who bought nearly the whole collection for a great price. It was a success as she got rid of things she no longer needed and made some extra cash.
An elderly couple sold their antique furniture pieces at a car boot sale. They were downsizing and didn't want to take all the bulky furniture with them. They were pleasantly surprised by how much people were willing to pay for their well - maintained antiques. This not only helped them financially but also made their moving process much easier.
It varies. There are different levels of privacy when it comes to geo - tagged photos. Some social media sites give you the option to make your entire profile public, in which case strangers can see all your geo - tagged photos. However, if you go into the privacy settings and limit it to a smaller group, such as only people who are mutual friends, then strangers will be excluded. Also, some platforms may have a 'nearby' feature where people in the vicinity can see your geo - tagged photos even if they're not your friends, but this can usually be turned off in the settings as well.
There are many interesting fanfictions about Geo from Megaman Star Force. Some might focus on his adventures beyond what's shown in the game, like his encounters with new types of EM viruses. Writers often explore his character development, showing how he grows from a regular school kid to a powerful hero.
One more thing to consider is that there may be some interference from other apps on your device. Some apps may conflict with Snapchat's functionality. Try closing all other background apps and then attempt to add to Geo Stories again. If this works, then you can try opening the other apps one by one to figure out which one was causing the interference. If none of these solutions work, it might be a more complex software issue within Snapchat that only the developers can fully address, so reaching out to their support is a good next step.
