Looking And Leaving.
I was reading this topic just now, and I want to put a comment about it here as well. Looking and Leaving is Okay, right? And generally no one really knows when you've done it, unless there monitoring their topic 24/7. Anyway if your looking and leaving, I feel you should be consistant.
Taking the example of the BBC forum, like in the above topic. Say you take a look at someones MOC. They're a bit of a noob, and its a standard inika build, with a bit of a rubbish colour scheme. You Look and you leave. Then you come across a new MoC done by one of BZPowers most sucessfull MOCers. Its a hot topic, with over 50 comments already, and you just have to post:
"OMG!! That is totally awesome! Can you add more pictures, can you addd instructions?"
How does this help them in anyway. Todays best MOCers know they're awesome, if its a smallish MOC, they'll probably add instruction when first posting the topic. Basically, your feedback wouldn't make much difference to them. Whereas if you gave feed back on the noobs topic, they're more likely to appreciate it, and make better MOCs in future. Why should the quality of something posted affect whether you look and leave or not?
