It seemed at first that Ping Goat, the blog pinging service, was down, which would be a real shame.
But it isn't really.
I think they basically got a little fed up with users simply copying and pasting the 'very long' URL, saving this as a bookmark and then once a week giving it a click, without paying any attention to their site - they do have tools!
Therefore you can fortunately still use Ping Goat to ping all your familiar sites: Technorati, Icerocket, weblogs &c. All you need to do is go to:
Notice it's a .net and not .com site now.
Simply fill in your blog details like you did first time you used this excellent pinging service and hey-presto your blogs just been pinged.
