Are you looking to get content up and get it fast. You can use the Autoblog Plugin from Elliott Back to quickly publish content.
The plugin, for wordpress blogs, can be used for good and for evil. This plugin, already mentioned by the author himself, can be used to setup spam blogs, and set them up fast. All you have to do is turn the plugin in on, setup a few parameters, and bam, your posting excerpts or full articles using someone else’s content.
Now if you’re going to be using this for good, you may only want to take excerpts from a few select blogs and post them every so often, not every day, like the auotblog plugin was made for. This would require you to turn on and turn off the plugin but would save you from having to explain to other bloggers why you’re using their content and not writing original stuff.
Overall, I would only use this if you’re desperate. Snagging someone else’s content automatically is a lot different than reporting with quick posts what the blogosphere is doing. Some people will get furious once they realize you’re taking their content and not sending traffic. You’ll need to tread carefully when utilizing this tool.
