If it's something I am very familiar with or passionate about I can write it in half hour. Poetry can be the same thing, however it doesn't always happen that quickly. When I am making food hubs I normally take photos along the way and so it takes longer until the item is cooked and that's when I write up the hub and upload photos. The part that can take awhile is when you are trying to find corrolating photos. I find that having the perfect picture for each hub is crucial. I didn't add links until about 5 hubs ago, I am liking that feature.
I think if you take a day or two to get a hub together it can turn out really amazing with quality photos and links. Anything extra you can add to your hub that might increase traffic is always a good thing.
Good luck to you!
