Make good use of your free time. While bloghopping during your breaks, go check out this huge list of sites where you can submit your RSS feeds. It also includes some blog directory listing sites you might want to add your blog as well. WP also recommends this All-Inclusive Ping List.
Most of the popular ones are already in the list like Technorati, Feedster and Icerocket but you might find a few more you might want to include into your WordPress Update Services list (commonly know as ping list).
Mine’s fairly generic:
http://rpc.pingomatic.com/
http://ping.blo.gs/
http://rpc.icerocket.com:10080/
http://rpc.technorati.com/rpc/ping
http://xping.pubsub.com/ping/
You can also use PingGoat or BlogFlux Pinger.
