First of all, I really like it.  I think it is nice.<p>Some questions, then some thoughts, and some prognostications.  What is the OpenID box?  I don't know what to put there. I don't have an openid.  Will openid be a link to the numbr?  Is it my email address?  I tried to click on the OI icon inside the box to get some help, but alas, I never figured out what that box is for and I'm a computer guy!  (A ha, just got to firefox and it told me my email address wasn't a valid openid.  hmph, did it still create?  Nope, not on the first page...)  Why does OpenID matter?  Let me use my Email address.<p>Well, it's a good idea. I still like it.<p>When I am in Opera and I click the "Create Numbr" button, nothing happens.  In IE 7, when I enter the url and click the "Pick a numbr on the Page" button, I get something about it not being displayed and then it was aborted and I see a blank nothing.  On my way to firefox (see above...)  Couldn't save my numbr...<p>What I wanted to save, was the number that appears in the link at the bottom of the first section on the cover of <a href="http://news.google.com" rel="nofollow">http://news.google.com</a>.  This number is the number of articles about the "top ranked" article at google.  It would show whatever google's algorithm puts there.<p>But it could come from Bing or any aggregator.  How popular the most popular story at Hacker News is, etc...<p>I tried with text too, but it said it wasn't a number.  Considering the one I <i>tried</i> to create, it would be nice to see what that article is, though because of this particular topic, you could do a little research.  For today, the top article may be obvious, but what was the world talking most about on Jan 17, 1987?<p>Of course the Internet wasn't around back then really, I mean, it could have been, but WebNumbr wasn't and we can't take WebNumbr back to 1987 to figure it out ...  okay, we could do research today about how many newspapers in the world had a particular headline for dates past, but that would be a tremendous amount of work.  It would be an undertaking so vast and incomprehensible that we just wouldn't even do it at all.<p>And here, you've created a piece of equipment using the power of technology, that without even thinking about it moving forward into the future is going to do that very task, with almost no human interaction -- 100% automated.  A task previously thought insurmountable, on your site is being done, right <i>now</i> 300 times an hour or so?  Could be thousands, millions, even billions really.  It <i>is</i> able to do it with a lot of numbers, like the dow, or a stock price, or the weather on a particular day or time of day and that's very, very cool and useful for a lot of people who track things using the web.<p>A lot of people have to track things, so they go to the web and type them in and write them down, or enter them into a database.  They don't have to do that anymore.<p>I can understand the technical reasons to keep it to numbers only and why the limitations are there now, but if you'll allow me to indulge in a bit of speculation about what types of things your users will request in the future, beyond what I've already mentioned, would be the ability to pick a particular number <i>within</i> a group of numbers.  The numbr in the top articles I mentioned was actually in a span with text in it, but it accurately picked the correct number (nice work), however, what if there are multiple numbers and I want the second one, will it still work?<p>What about dates and times?  Maybe you want to track the numbr of days since the last injury, which is a number, but what if the only number on the page would be the date of the last incident?  Like the X's on one of the keep motivated articles we take in once in a while.<p>You also may want to alert people if the values change, I'm sure you've thought of that. Give them thresholds to fire an event or call a web page or post to a page, etc...<p>Those are just some ideas.  Keep in touch.  Remind us of you going into the future so we can monitor changes and keep track of how things are going.
