I used the ping_weblogs_com found and described at Get Noticed by Pinging site. The referenced page also lists a number of services to ping.
Adding a ping to weblogs.com was reasonably simple, except that I forgot that I can't do a $ping_weblogs_com
in the text article, but had to do it as part of a flavour file.
And as I didn't want to do it as part of a regular article presentation, as it may extend the page load times, I had to create some separate
flavour files. I then activated the
plugin in the story flavour.
Now I'm all set with to ping Weblogs.com.
BrutalHogs has a ping flavour to help a little with
the manual ping process. But I think that Ping-O-Matic probably
takes care of most things, even if it is only manually for now.
