As WP users will know WP will automatically notify site update services such as pingomatic but those who blog Hot Trends will know it is instant traffic that is needed and I'm assuming that it can take these update services sometime to call and by that time Hot Trend is no longer Hot!!.
So here's my query. To obtain instant, albeit short term traffic, what's the best way to go: use services like pingomatic or make announcements on sites like Digg? If the latter what sites would Warriors recommend?
Many thanks for any input.
