It's not bad, but it will slow you down tremendously if you learn how every framework or library you use works. It's a psychological barrier - just as you (probably - I'm going on the odds here) don't really know how a processor works, you really don't need to know how a framework works. By all means, dig around in the frameworks, but treat that activity like the hobby that it is.
