I think the first clue is: People don’t really upload models to a personal Gallery page on this forum either.
That's in part because...
It’s intimidating to put your stuff up for the general critique of others (for one thing),… but it’s also takes extra courage to do so when the standards have been set so high given the fine works of Cotty, Box, Dave R, JimHami, Liam, Ian, etc…
You can find examples of folks almost apologizing in advance of uploading their first model into their own gallery,… saying something similar to… “Here’s my model, I love SketchUp, but I know I’m not as good as so many other users…”
That pressure is real,… but not new, I can still recall seeing fellow class mates in tears during really light and mild critiques back in my art school days. So I know many people tend to hold their creative efforts very closely.
Anyhow, this video shop tour adds in the extra element of folks personal space… now it’s not just a critique of ones work in a SU forum Gallery thread, there’s an added element of economic standing as well.
“Well I have a grungy shop,… it’s probably not as nice as what others will be posting up…”.
“I don’t live in a very nice place, it too messy…”
“Don’t want to be seen/heard on camera…”
Change the words around as you may like here… I’m just trying to offer a quick preview on the internal monolog that takes place far too often.
This doesn’t cover everything but it does factor in to a certain degree like or not, as the frailties of the human condition seem to require it.
… and I guess that covers my main point anyhow.
For the world of the less sensitive… Hey it’s a video… that takes time to edit… and probably many folks are looking to craft a nice movie. with the majority of the uploads coming in on the last week (/days).
I DO think it would also have been helpful to have a few token examples already uploaded… and probably one that shows pretty shabby conditions,… so the whole self-conscious stuff can be set aside for just having fun… as is the original intention here, I know.
