there are tons of them, worth the try? you need to see it yourself (but I dont think you will have a more than 10-15% from them)

only upload - glstock, scanstockphoto, signstock, allyoucanstock, photokore, superhug, stockfresh (last one 1 click to all)
upload and 1-5 clicks (per batch) - veer, 123rf, photodune, yay, pixmac, panthermedia, canstockphoto, irockstock, crestock, zoonar, mostphotos
upload, clicks, categories - deposiphotos, bigstockphoto, featurepics (last one no categories but one each time)

over 200$ in 2011 - canstockphoto, depositphotos
from 150$ to 200$ in 2011 - veer, photodune, panthermedia, bigstockphoto, isignstock

Because I value my time? Better to spend two hours to make $100 a month than a week to achieve the same result.

(There was a discussion on here years ago about the effectively hourly wage people got, and I seem to remember many microstockers actually making less than minimum wage...)

you need to pick the right small players like I have said and also told you some numbers..

I will add that I have made around 10k $ in 2011, 1700$ were made in agencies beside the top5 (SS, IS, FT, 123RF, DT)

the time I have spent was worth? in my opinion hell yeah it was and why do I say this? because I wasn�t going to shoot/edit/keywording other stuff so I was uploading/submitting as I was browsing websites, watching TV, facebook, listening to music and this forum, so why not?

if you have plans for shooting more I would say shoot more not uploading to more agencies, you need to check agencies yourself and how they work for you, the majority of them are very quick

Although nobody is so naive to believe this is a passive income forever, we have hopes (and proof) that the same old pictures will keep on selling for many years. How can one even calculate an hourly wage?

Time also matters. If you need 30 hours to made 1700 $ you`ll have a perfekt hourly wage.  if you need 5000 hours to made 5000 $ ...

I'm sure you realize how absurd that comparison is
