Once upon a time, a writer needed stacks and stacks of books if they wanted to have reference material available. These days, you can simply use internet resources to look up what you need to know.
There is really no excuse for misspellings, poorly researched articles and horrible grammar from writers on the internet.
If you’re having problems coming up with things to write and write about, it can help to read what other people are doing. The Letter Project is a project started by someonw who wanted to practice their letter writing skills.
Maybe you don’t care about writing letters, but perhaps you could do something similar? Maybe you want to really press yourself and offer to write a short story about the person (after they give you an occupation and a few other attributes)?
There are many variations on this theme that you could do, try to come up with a few more.
