I've worked some more on my SumIrUp tool [1], which can generate a list of language templates with one-line descriptions for a new article. All it needs is a starting point, namely this article in any language. From there, it will spider all the language links, and gather the initial paragraph/sentence of each article. It then generates a copy-and-paste-ready text, including language links.
I was wondering - why not link to this tool in the instructions text for new articles? There could be a link to this tool using the name of the page to be created, and en.wikipedia as default. If an article with that name exists on en.wikipedia, it will generate said list of one-line descriptions which can be copied into that article. As this is exactly what commons articles/categories *should* contain, it might be a huge help.
