No. Just if you get the urge. I used to heart them all as a way of saying thanks for taking the time. Then it got like i was trying not to hurt feelings or play favorites. But it's a pretty tough crowd here no one expects all their answers hearted but enjoy getting best answer. If I'm wrong someone will tell me. Rest assured.

It's polite but that doesn't make it mandatory.

I think you should do it if you appreciate the answer.

I do. Unless the answer is retarded, off topic, or they insult me 🤷‍♀️ It’s not mandatory but I feel weird if I don’t 😂

I heart all the answers to my questions unless they’re rude. I feel it’s a way of showing appreciation for people taking the time to answer. I also try to comment on most of the answers as I find it’s a good way to get to know people and just have fun.

Thank you for BA award. I'd also like to thank my agent and of course mom and and just every body i do declare(looking for any Oscar here)
Seriously, I'm glad you liked it.

I heart what I heart.... And that isn't a lot

I always felt like it's a good way to acknowledge comments.. especially if you don't reply to them.

It’s completely up to the discretion of the poster

Hahah wtf

I usually do

Not mandatory at all, but some people do.
