The Reddit API’s rate limit is up to 60 requests per minute. It allows a request to up to 100 items at once. If you have less than 100 items to request, you can do it all at once. For more than 100 items, you need to make multiple requests, making sure that you don’t go over the 60 requests per minute as per the rules.

There are various types, but JSON is almost an industry standard nowadays. Grab the content as follows: As far as JSON response of Reddit API is concerned, the response dictionary is usually very loaded. The first thing you can check is the dictionary keys. After the keys, we can grab the piece we want, and move progressively.
As described in the docs, try specifying a count:
http://www.reddit.com/r/all/new.json?limit=30&after=t31qa3v3&count=10
Basically what happens is that reddit needs to know how many posts you've just viewed in order to determine what the starting point of the "previous" listing is. So if you use the above example, you're telling the api to start on the article that comes directly after t31qa3v3, display 30 new resuults, and give you the id of the article 10 spots before t31qa3v3 to act as your before value. If you don't include the count, it won't know what to use hence the null.
