What's the correct capitalisation, 'citoid' or 'Citoid'? The article uses both seemingly interchangeably.
Topic on Talk:Citoid
The service is 'citoid' and the the extension is 'Citoid'. Mostly due to capitalisation conventions for node.js libraries versus mediawiki extensions.
So the introductory sentence is, in fact, incorrect – “Citoid is a node.js service”?
Not necessarily. Common sentence case rules say that even if a word is normally lowercase, then you can capitalize it at the start of a sentence. Thus "IPhones are expensive" and "An iPhone is expensive" are both correct.
I've modified the wording on the page. Hopefully it's clearer?
