You could use a sandbox if you want to have a personal page. I use mine for a wide variety of random stuff, and it doesn't need to be comprehensible nor have any form of structure, it can just be a place for you to put half completed posts and ideas. Here's yours, just create the page and you're ready to go. I'd advise on adding a link to it on your user page though, else you might struggle to find it again.

As a side note, make sure you don't overuse it (this applying for all forms of personal pages). Anything deemed as edit farming by the admins won't end well on your end.
