[metasean]

dpweb:

- mentions the term that this concept falls under (no where on the OP's page, so he may not know that there is an entire set of software, plugins, etc that does this)

- provides one alternative implementation

- adds commentary related to why such services are necessary, and that they should be able to be monetized

So yes, he starts off with something along the lines of "I did that before you!", but he doesn't use a condescending phrase, and he provides additional useful information.
