Does this site respect robots.txt?<p>Does it render javascript content (so e.g. <div ng-view> angular sites work)?<p>Does it exclude or include comments... if I watch a blogpost with comments will every new comment cause an alert or only blogpost changes?<p>Will I get a notification if the page briefly 500 errors when you hit it, or does it have to get a 200 before it reports a change?<p>Will I get a notification if a page disappears entirely?<p>Does it scrape only once per day or more often and alert only once a day?<p>What user-agent does it scrape from on the off-chance someone wants to block it?<p>Does it diff binary data.. for example, if I ask it to watch an image url will it hash the image and notify me when it gets updated?<p>Does it auto-detect pages with rss feeds or pubsub feeds and subscribe to them?<p>Does it understand twitter so if I watch a user, it only alerts me of tweets, not e.g. a change in the number of followers?<p>Does it have special code for any website whatsoever?<p>Is the webpage parsing/diffing library / algorithm open source somewhere?<p>Is there a monitization plan, and if not how can I trust it won't vanish?<p>Is there a limit on the number of sites I can watch?<p>I like the simplistic design, but it would be nice if there were more information.
