BTW, I like to do a review on this tool. I think it is super cool tool. Using SteemNow for latest posts but that one is not the best for older posts than a hour or so and does not have the tag filtering. Your does. Can you tell me what the oldest post is that can be filtered on? Also, since your have more filtering options in your tool, I suppose you must have a good server running, otherwise it'll become slow when some more users are using the tool, or?
