I really liked the design and example graphics. But I don't know how it actually works because I am blocked by a request to sign-in using Twitter or Facebook.<p>I also think the site itself is beautiful, but I feel that I need to provide some constructive criticism.<p>* On the main page, there are links to for Twitter and Facebook, each link to their respective PHP page in the under beta/. The Facebook link works exactly as I would have expected (redirects me to a page at facebook.com). The Twitter link (infogr.am/beta/twitter.php) redirects me to "infogr.am/beta". I was expecting it to redirect me to a page on Twitter that allows me to authorize your application to access my data. I have to click a second link for that. All in all, I think this is just a small bug.<p>* With text like "it's super simple, just try it!" I really was expecting to "just be able to try it", but when I clicked the "Start Now!" button I was greeted with the need to sign in using either Facebook or Twitter. Having to log in is not the same as "starting now". Definitely not what I was expecting.<p>My recommendation is to change the wording so that it is completely understood that to even try the service I need to log in with my Twitter or Facebook account, or allow me to just use the service, and when I wish to save something, prompt me to login. Personally, I recommend the later.<p>* Concerning the use of social media sites as login providers. There was no mention in the "Making infographics is very simple!" section that I can use my Twitter or Facebook data to create these infographics so why does Infogr.am need access to who I follow and my tweets?<p>Now if you are using Twitter and Facebook as login provides because its easy, I completely understand. Then do the user a favor, on the "/beta" page, let me know right up front what you are going to access, what you are not going to access, and why you need anything you are accessing. I say this because clicking on Facebook login button redirects me to a Facebook login page that doesn't even tell me what you want to access.<p>If you want access to my data, be completely up front and honest with me. Twitter does, but do I really need to click through two pages to find this information out?<p>All in all, I really like the idea, and look forward to trying it, but I am going to wait till I don't have to use my Twitter or Facebook account to log in.
