It's not very slow to scrape a website. Works quite well. Your app would appear like any other browser to the site. The trouble with that is that it breaks easily when they change something on their site. Doesn't even have to be a malicious change.
That's good to know, I'll look into that some more. I was thinking that it might be slow if I'm having to scrape each page, every time a user changes categories (or something similar).
I completely forgot about that :(
Well, it's as slow as the website you're scraping. Could actually be faster if you don't have to execute a lot of bullshit JavaScript. And for the rest clever caching should help.
In terms of technology you're looking for XSLT, Xpath, CSS selectors and whatever parsers are available for your language of choice. Don't ever attempt to use regex for scraping.
You've given me a great jumping off point, thank you!
