That depends on the playstyle of a jungler, really. If they're counter-jungling, then Wriggles is a good choice, but less so when they're gank-heavy CC monsters. It doesn't help much that Wriggle Wards only have half the duration of a normal ward and Sightstones are pretty much a non-option for early junglers (at least you have an infinite amount of Wriggle Wards, but only one every 90 seconds).

The main problem with Wriggles is that Spirit items are more popular and Wriggles still has to struggle with its old reputation.
