Do you know the website like similarsites.com ? other than stumbleupon?

Well, Alexa has a ‘related links’ tool if you search for a particular website, but I searched up Fluther (.com) and it was surprisingly inaccurate. It lists Digg, Twitter, and this site called Betamarker…

I also looked up Design Bump (which is a Digg-like site, but geared towards designers on the web) and it was marginally more accurate; it listed sites that also deal with design, but many are blogs and not similar design-related social media sites.

I believe websites that offer some sort of similar-site thing tend to do a poor job…either because they collect related URLs in an automated way that works out badly, or they have a user-rating system that doesn’t produce accurate results because there aren’t enough people using it/

a giant one

I am not totally clear on what you question here, but is this maybe what you are looking for?
It’s an add-on for Firefox.

“Discover recommended websites, videos, images, products and more – all related to the site you are viewing – in the Discovery widget.”

similarsites.com is a website used to find the site similar to what u enter in search field on that site.

Google is good for that , it sounds as tho you are plugging the site ? If you know what type of site you want tell google to find it .
