While it is a kick to get praise for your project, it is the advise I prefer. I've received more responses when I pose specific questions. 'What do you think?' is not nearly as good as 'do you like A or B?'
It's also a kick when you give someone an eye-opening piece of advice that they appreciate. I'm sure some people have thought 'no-duh' to some of my posts, but occasionally I've truly helped someone out. As long as we don't get pissy when someone gives obvious or even dumb advice, posts in this forum will thrive.
BYW...I'm just as guilty as the next guy for lurking.
