Photos sharing - Free vs Paid service..

Hi all

I want to write about the ONline photo sharing ..i was using a yahoo photos which was ...free..



but not they wanted all this stuff to be moved out of the yahoo to the flickr and other stuff..

but they are not free they are all to paid after some more time and also i couldnt not download in this ..



i have questions on this ..

1. Are these service providers customer friendly ??

2. Why do they provide us a free service and then push us to a paid service



are we getting trapped --



In future do all this mail services and all will become of same nature ???



i think any free service ..we are using now to be reviewed to avoid any thing like this in future...
