Is it me or is eclipse a piece of s***: From the introduction: I know eclipse is free, but come on, I don't know how people actually use this piece of s**t to build software. I like open source as much as the next guy, I just like "high quality open source" which may be an oxymoron. NOTE: this is a blog posting followed by nearly 100 comments, almost all of which agree with the blogger.***WARNING: Contains a large amount of profanity***
