Those two compete less than you might think. Snipshot is an easy tool for ordinary people to tweak their photos; Splashup is aiming at Photoshop.

The link says the photos are edited with Snipshot because they are edited with Snipshot. All I need for my site is something simple.

The link is there for the additional reason that you are still promoting Snipshot. This is good news for me, because integrating Snipshot with ourdoings.com is in my plans, and I wouldn't want them to disappear. That they recently added a Pro version seems a good sign.
