TINT I unfortunately have to agree with you here. its a shame because i think reactions are cute and funny. I'd like to start off by saying i don't think its a bad thing to have a 'like' system such as the one here on Sheepish, i just don't trust users to properly handle these 'like' systems. Even though i don't see the thumb rating and reaction system an issue currently, if this site grows, the rating system could absolutely change or, at worst, destroy the comfy-esque nature that's so appealing about this community.
if the site encourages (whether intentional or not) posts of a certain type that appeal to numerical interaction (such as number of likes or number of reactions) instead of genuine discussion, I'm concerned that the current and/or future users of this site may change the way they post-- whether that be consciously or sub-consciously-- in order to gain more 'points', however that may look.
This might all be incorrect and the site will stay this way for the foreseeable future, but i've seen too many social media sites and communities (many of which i've called a home at one point) devolve into a contest or game to see who can get the highest score instead of what's important; fostering a community and the meaningful interactions surrounding said communities. Even the innocuous Point display here on Sheepish (viewable through the profile screen) could be seen as a 'High Score' and a source of competition, especially because it can be seen by other users and not just yourself. I'm sure Reddit and the effects of it's Karma system on the content and quality of posts will come to mind for many of us.
Remember, we are living in a 'permanent september'. the people who we interact and form communities with online is never guaranteed to stay and therefore the 'communal essence' is never guaranteed. Let's enjoy ourselves while we can and stay comfy.
TL;DR: keeping likes and reactions engenders the 'gamification' of conversation which may lead to the erosion of communities through users competing for a high score instead of focusing on meaningful conversation.
