Its a very interesting feeling. On one hand Im proud because Lemmy has come so far. Two years ago there was only one instance dev.lemmy.ml and no federation. On the other hand disappointed, because some people are unable to appreciate how much time and work I put into this project. Its especially ironic that these attacks are coming from people who pretend to represent the working class.
