"I love icecream very much. Normally people wuld like to eat icecream in summer, few people were seen eating icecream in winter. But I will, and I found that is very excited to eat icecream in winter."
There are grammatical errors and misspellings all over this.

Maybe the problem is that people are writing essays in the language they are learning instead of in their native language like it suggests on the home page. If that's that case, then this could be a good tool for essay writers to get feedback on their work. It needs to be clear, though, whether people should write essays in their native language or in the language they're learning. Maybe there could be different sections for each type of essay? Then you could also read essays in your native language written by students of the language and give them feedback, or you could read essays written by native speakers of the language you're learning.
