Thank you for your interest.
If you ask for market share, we try to be the first website when people need information to look for. However as content, we are trying not to compete but complete Wikipedia. Wikipedia is very slow to include information, you can see the comparisons under "More Problems we solve" subtitle of the post. Wikipedia is for objective information, we are for information gathered by experience, written in simple language and with unlimited and specific topics. HEDE is a combination of many wikis in a single platform, basically, Wikia+Urban dictionary. You can see who we compete with under the subtitle "Similar Projects" on our post.
