Scrapy is written in Python. This looks like a Ruby focused article. It's even written in the title, no need to actually go and read it. I'd say your suggestion is simply off-topic here.

As for Scrapy itself, it's a big framework, written on top of even bigger framework which is probably better described as a platform at this point. I've used Scrapy in a couple of projects and I also worked with Twisted before, which made things significantly easier for me, and it still was quite a bit of a hassle to set things up. IIRC configuring a pipeline for saving images to disk with their original names was kind of a nightmare. It does perform extremely well and scales to insane workloads, but I would never use it for simple scrapper for a single site. For those requests+lxml work extremely well.
