I feel I've been struggling with Rails for a while now, at the time I've got excited about the promise Merb brought, but the merge hasn't noticeable changed the way I work. Mountable engines seems like a big hack to me and I some times struggle with class reloading in development because of it. Sinatra got mountable apps from the beggining because of being closer to rack, one could just us rack mount to inclue another app. I worked for a while on a big Sinatra app and it was a pleasant experience allthough Sinatra provides too little, but latelly I started a personal project on Padrino and a found a joy I havent felt in a wile using the languaje and tools I learned to love, Padrino is like I've allways wanted Rails. I am gratefull of what Rails has taught me, but I want to get off the bandwagon, Rails has grown to big and complex for my taste.
