GNU Wget in decline?

You can do everything you can do with wget - and more - with curl (though it seems to be tending downward on that graph... not very sure what may be the reason for that).
Nice text on HTTP scripting: http://curl.haxx.se/docs/httpscripting.html
And a total aside: http://ifconfig.me/ is extremely awesome. I probably end up using 'curl ifconfig.me' about once a day at least.
Here's a nice page detailing the differences between the two tools -- apparently written by the creator of curl itself:
http://daniel.haxx.se/docs/curl-vs-wget.html (and a more comprehensive chart with additional tools: http://curl.haxx.se/docs/comparison-table.html )
It sucks however, because you can't redirect its output to another program and have to write the output to the file system (more I/O).
In short, I use both.
I think there's only one conclusion:
The web itself is in decline.
Incredible, I know, but this is science.
