I agree with most of the comments.
Registration is an absolute killer, even if it is EEtimes which some may already be signed up for.
No one like to be sucked into the "sales funnel" which coincidentally we mentioned on the AmpHour yesterday.
Before I had ever logged in, I got spammed by EEtimes with a datasheets.com product listing. I was not impressed by that.
And not being Google indexed is silly, although the site is new so it maybe indexable but not listed yet?
But even so, I hate finding datasheet links on Google search and then finding out I have to register to get it, or wade through a page riddled with ads, as is quite common in this industry, to point of wanting to scream sometimes.
If the express aim of the site is to give engineers datasheets, you should do just that, no mess, no fuss. And preferably with simple straight direct URL links I can possibly cut'n'paste into project documents.
And yes, the parametric search criteria aren't very useful or well thought out, I'd much rather use say Digikey for parametric search in combination with findchips.com for price and availability.
I'd LOVE to have all that in the one place, so the concept is sound, and the data seems to be there, but it just needs some work and more thought to make it the truly useful one-stop-shop they are hoping for.
