Care the feeling of KM tools user

In my last post, you have found that I only spent few minutes to reject a new km similar tools: ziki A looks good service which can help you to organize all your digital contents.
what's happening?
The tools didn't give me good first image. I didn't try more on the service, but once I found that under my most favorite tag, there's lots of unrelated info, I have a direct feeling that this tools won't help me but can only waste my time.
Garbage in, garbage out. As lots of guys know this famous statement.
So be careful to your km tools, if your tools give their users a first feeling of garbage. Pls knee down and pray for your investment on these tools. I can bet you won't get them back.
