For me, liking never really did much. I'm sure it helped with super small accounts that don't get much attention... but to me, it seems that people just post shit and walk away, let it collect likes and rarely look at who liked it.
They're far more interested in who is sharing what they had to say, or commenting on it, because that validates their reasons for sharing, especially if it's a blog post or new product.
Even retweeting seems to result a lower engagement rate, because it's so close to (and probably as pointless as liking) because it's a single click with minimal effort. I think that's become pretty transparent for Twitter users, especially as more brands just dump links and use it as a way to hope people click-through. Also remember Twitter "likes" used to be Favorites, where you'd save a favorite post and it wasn't just used like Instagram - which is what I'm saying.
If you're smart with who you choose to like, that may be more effective.
Maybe one day I'll try again, I was able to grow my Twitter account pretty quickly but the engagement was just too low to bother, even though to be honest ... I could use the YouTube views from the videos I make and share. Though YT is growing organically because of the quality video I produce, but that's a whole other story.
