isProbablyReaderable

How difficult would it be to implement isProbablyReaderable(doc, options) (from https://github.com/mozilla/readability#isprobablyreaderabledocument-options).

This would allow to check when a webpage is actually interesting / relevant for scraping and save on speed.

Would this be hard to implement? I could also try working on it.

It's not difficult to implement in that way, but I'm afraid you won't get any big improvement in parsing time (now typical article processing time is 0.1-0.4 s per page), nor it's reliable, or, to be more precise:

• If you use minScore check, readability algorithm is completely the same but without cleaning phase, will take almost the same time.
• If you could only check HTML, it's completely unreliable.

Oh I see. What could I do to use readability to check if a webpage actually has like interesting content?

Where an actual article passes this check and something like the google homepage doesn't.

The main check should be whether there's something to read: text with length starting from 300 chars. Ideally, 500+ chars.
You can check this after processinging with readability: just convert to text and check the length.
