MG The output format does indeed seem to have changed since this was written - replacing the regexp line with
set RE {<blockquote><b>(.+?)</b>}seems to get it going again now. (Though, the comments in the HTML code ask you not to web scrape, and to contact them about their API instead - I just emailed, will try and comment here again when I hear back, hopefully it'll be something that can be done simply in Tcl like the above.)AF: I added an example for using bit.ly to the tcllib rest module [1] which may be a good alternative[mw]: This example uses the tinyurl API instead.
