Who said gossips? "Stories" have and utterly different meaning to me.
Journals stick around. Letters stick around. Notes stick around. They are important. We evolved to write, not just talk, and reading back who you have been 10 years ago, even if it's just a plain entry, can be surprisingly useful to maintain a healthy soul, especially in times when you think things are slipping away.
Take away the option to remember, what are you left with?
And no, I'm not exaggerating. No one scrolls back any more; yesterday deliberately out of interest, and I disagree with this from the bottom of my heart.
Whereas writing something which will be kept on the public historical record for all to see forever leads to both conscious and subconscious self-censorship and can be misleading when trying to "read back who you have been 10 years ago" because what you wrote may not have been what you were really thinking.
The ephemeral nature of the spoken word and the historical nature of the written word both have their advantages and disadvantages.
This is sad. The whole thought; the whole idea that I can't read things back; to post apparently meaningless "stories" into the void.
We have/had blogs for this, with the exceptions that those are not ephemeral. To read back you own stories, your own mistakes are invaluable lessons and not having the option to do this, because you depend on a service provider, where you have no control saddens me deeply.
Get a WordPress and make posts disappear automatically after X hours - this is ~5 mins to set up and this way you can both keep and retrieve your stories from the public.
Once this is done post to Snapchat from that blog; via webhooks, bots, whatever. Yes, right now, this is tedious and requires technical knowledge, but the goal is to own your data. But do not store the only copy your original content somewhere where you have no control at all. (See http://indiewebcamp.com/POSSE for the whole idea)
