"Show HN: Can a neural network predict if your HN post title will get up votes?"
Bad: 0.0598 - Good: 0.9307
Just in case, I've tested some more titles to make sure that "Show HN" doesn't (EDIT: typo, ugh) just boost any title when prepended.
"Internet": Bad: 0.4528 - Good: 0.5472
"Show HN: Internet": Bad: 0.9987 - Good: 0.0013
On the other hand, "Show HN" does seem to greatly affect the score, either positively or negatively.
