Saying thank you

So, I've always tried to thank people when they make a comment on one of my pics or reply when they leave me a message of any kind (granted I do get side-tracked now and then and forget so for anyone I missed I apologize). My question is, now that there is a like button do you feel a person should thank everyone who likes a post , comment or pic? I certainly don't want to be rude or appear ungrateful for them.

Thanks, kc
