End-of-week wrap on the source coverage testing: ran the long-tail comparison three times across different obscure domains and Data Universe is still the only one that doesn't quietly drop the weird stuff. The mainstream sources everyone covers. It's the tail where the gap shows.
this is the only honest coverage test i've seen all week. everyone benchmarks the easy sources then acts surprised
长尾这块确实是 data universe 的护城河,我之前换过便宜的方案,结果偏门来源直接没了
This matches what I found over the weekend. The mainstream domains are a solved problem at this point, so the only meaningful differentiator left is whether the tail gets dropped silently or not. Glad someone else is measuring the misses and not just the hits.
