Before I sign up for anything new now, I ask myself one thing: would I still want this if it cost money next month? A surprising number of tools fail that test immediately, which tells me I was only interested because it was free and new.
To actually answer that question I need something to compare against, so I check AIDirHub first — seeing what else exists in the same category makes it obvious pretty fast whether a tool is genuinely useful or just novel.
Cuts down on impulse signups a lot more than I expected.
