Scan the table for products with engagement ratios above 0.30. Click through to the ones that share the most category tags with Modelence App Builder. Ignore anything with a ratio below 0.10 unless you have a specific reason to look.
Not yet. The current index captures launch-period engagement. We're evaluating ways to track post-launch traction, but it's a different data problem and we want to get it right.
Check the comparisons section. We auto-generate side-by-side pages for products that share categories and have similar traction levels. If the pair you want isn't there, the products might be too far apart in engagement to make a meaningful comparison.
By community interest score. Higher score means more people engaged with the product at launch. We show engagement ratio as a secondary metric because it separates one-day hype from products that generated real conversation.
Launch-day attention. It's a popularity signal, not a quality score. A product with 2,000 interest might be worse than one with 400. The number tells you who showed up, not who stayed.
Discussion threads divided by interest score. Above 0.30 is strong. Means people cared enough to write about it. Below 0.15 is a warning sign: lots of eyeballs, not much substance. We've found it's the single best predictor of whether a product has staying power.
