There's a new curation tool in town, it's called Steemlookup. Check out their introduction post and give it some love. This has to be one of the most feature-rich filtering tools for the Steem blockchain, especially useful for people who want to discover exceptional content.
Finding Good Content
Steemlookup allows you to filter out specific content, based on the parameters you've set in advance. On the left hand side, you'll see a bunch of filters, which you can adjust to only view specific types of content. It's extremely easy to use and you'll also have the ability to exclude certain users, tags and words. I'll offer some possible use-cases below to get you started.
Maximizing Curation Rewards
We can set the parameters of Steemlookup to find posts that have been published around 30 minutes ago, while also filtering out posts that have not received any rewards. This would allow you to maximize curation rewards, since you're able to filter out posts with possible high rewards in the future.
Filtering out content, based on the number of comments it has already received, could also be a good indication that a post will receive additional upvotes in the future.
Finding Undervalued Content
With these parameters, we're looking for posts that were created between 6 and 7 days ago. You can easily convert seconds into days and vice versa, by just typing in Google '7 days in minutes'.
We're only interested in posts that have a minimum of 400 words and have a total payout of less than 2 SBD. You can easily adjust these options to your liking
I have noticed that it does take quite some time to apply these more complex filters. Filters that yield huge result sets are a lot slower. (Credits to 
Find Spam Content
In this example, we're looking for posts from authors with a reputation of at least 30, who post content made up of only a single picture, with less than 20 words.
I've limited the search to only show posts of maximum a day old, this helps with performance. In this case, I wanted to focus on posts that have at least 0.5 SBD in post rewards.
This is far from a perfect example, but you can see that we can filter out the obvious spam posts pretty easily. In this case, we're targeting spammers who've made money and have not yet been downvoted (hence looking for rep >30).
Conclusion
I would really like to see a lot of people make use of this tool, it could greatly improve the status of Steemit if more people engaged in curation. One of the things I'm personally going to try out, is try to find undervalued content close to the 7 day mark and show it some support.
I'd love to see other people come up with different use-cases, as I've only scratched the surface with mine. I'm sure that this will become a standard curation tool for many Steemians.
