It leads to interesting connections sometimes – you’ll be reading a page – see the little “we have links to this page” icon at the bottom and start clicking to other pages that have something to say about the page you are looking at.
I haven’t noticed the bandwidth hit at all (it runs a little query in the background for every page you go to). And I’ve been somewhat bandwidth challenged this week as my satellite service has been non-existent since Tuesday. I’ve been living off of my EVDO card – but I’m right on the edge of broadband service, meaning sometimes I can get 50Kbytes per second download times and sometimes just 14Kbytes – depending on the way the wind is blowing.
I am at this point giving serious consideration to a dedicated T1 line – a bit pricey, but I want a wire going to my house with no quota’s on usage and guaranteed bandwidth.
