WordPress Web Scraper Plugin/ other options?

Hello World Of WordPress,

I would like to make a wordpress site that automatically pulls certain content from the internet and puts it as a post in a pre-determined location on my wordpress site. I would like to have a section on my site for twitter posts, facebook posts, and hopefully any other source of content I can think of. Which methods should I use to do this? The content I pull will be used solely for presenting information purposes, which brings me to my next question. Does anyone know if it’s legal to do this? Also any recommendations of site templates, other plugins, sources of information, etc. would be greatly appreciated. I’m new to wordpress and don’t know much, so please bear with me. ?? Thanks

Adrian
