I use here... then Pinterest, Flikr, Scrapbook.com, occasionally ScrapStacks (It runs super slow for me for some reason!) and then I bounce between different private galleries on FB - usually posting at 2 (I prefer the private groups over public groups). If it's a double, I post to the Double Layout Digital Gallery.
Pinterest is a big one for me... an example is if you post on Scrapbook.com and they pin it, it gets a lot of views/re-pins. I have a lot of followers of my tutorials at Pinterest too, so I might combine my layouts and Tutorials into one board.
As for Flikr, I get comments on my layouts when I post to Digital Scrapbooking Groups or the like. I always add mine to The Daily Digi Group, and then pick a couple random groups on there. Some layouts have a huge view number, while others not so much it can range from 30 to 150.
For inspiration for me... I use Pinterest and Flikr. It's so big, and so many different layouts, and I usually get inspired by the creativity there. It's so easy to search and then just scroll, lol!
