- You don't get any/sufficient recognition for your contributions
- deletionism is a tremendous problem on Wikipedia, for two main causes:The stuff you wrote can be deleted anytime by some random admin/opposing editor, examples at: Section "Deletionism on Wikipedia".
This also possibly leads to Edit wars in the case of sub-page content (full page deletion is more clearly arbitrated).
- tutorial-like subjectivity
- Scope too limited, and politics defined. Everything has to sound encyclopedic and be notable enough. This basically excludes completely good tutorials.
- Insane impossible to use markup language-base talk pages instead of issue trackers?! Ridiculous!!! That change alone could make Wikipedia so much more amazing. Wikipedia could become a Stack Exchange killer by doing that alone + some basic reputation system. Some work on that is being done at: www.mediawiki.org/wiki/Extension:DiscussionTools, already in Beta as of 2022.
