Reddit is great. One thing people don't realize is that reddit barely requires you to do anything to register. A name and a password that is not even verified. Of course, they have spam filters that track your IP and monitor how many times you register or post, and also their community does a fairly decent job of weeding out any self-promotion, but you can still get good surges of traffic.
A few things I learned from using Reddit:
Long Titles that are very specific and offer up a cliffhanger question: I noticed a trend of long titles getting the most views, and usually if I wrote them in a bizarre way where you would just have to click on it or you would spend the day wondering what the hell it meant, I would see a lot more visitors.
Homepages, label pages, individual pages...
Sure you can only post a page once, but you can also post each individual post, label searches (i.e: www.yourpage.com/search+label=dogs) as a page. This is a very useful tactic because, you could put that page in reddits "dog" section, or if your label is "power tools" you can put it in the appropriate reddit section. This opens up a ton of new options to find people who are specifically looking for that particular topic. I have noticed a huge increase of CTR when using this method too, because you are getting a target audience and not randoms.
7 minute wait period:
Usually you are told to wait 7 minutes to add a new reddit. Sometimes, (especially with new posters) it will say your post is unpopular or something and make you wait for an interminable amount of time to add a new post. Register as a new member (like I said this takes a few seconds) and try again.
Reddit is good but it also isn't very fair (most of life isn't). On the one hand, it allows the community to determine the rankings of posts. But also, it is VERY hard for new posters to get votes.
The most "ups" I ever got on a Reddit was on a post about Kurt Vonnegut's thoughts on Class Warfare and Wealth inequality. These topics are great because right now people feel very stongly about them, and it's nigh imposible for people not to put their two cents in about it (meaning traffic).
Each Reddit area seems to have its own demographic, you will find a very different crowd in the "WTF" area than in the "News" area, and you should know what type of audience you want, when you decide where to post.
