Review on A-Parser by James Wonsley

The ease with which you can use it, its speed (even when parsing thousands of pages per second), how easy it was to setup for my needs and all in one solution! Nothing really - I do like that it's open source and has a lot of great features built into an excellent platform. I think there are some minor UI issues but nothing major. If your interested in building crawlers or doing high throughput tasks then this is probably what you need. It solved several problems at once including being able to crawl very quickly from scratch while still having access to a number of tools to help extract data from webpages.
