It's clickbaity because you have to click to find out if their opinion is highly positive or negative. It sounds like it's going to be answered by "... terrible" or "... great!", and that it's phrased that way to make you click and find out.
Granted, once you click you find out that's not why it's titled that, but you still feel baited into clicking to find out. A better title would be something like "I tried Haskell for 5 years and here's the good and the bad", or something like that.
It's hardly clickbait. Clickbait would be a purposely inflammatory or exaggerated title to get you to click the link. This is the complete opposite of that.

I think you just stated the purpose of a title. Wiki says clickbait is:
> "... relying on sensationalist headlines or eye-catching thumbnail pictures "
There's nothing sensationalist about. "I tried Haskell for 5 years". It's rather banal.
