It’s Saturday afternoon, which means it’s time to review notable community blog posts and tutorials from this week. We have some great reads this week: essential mobile apps and themes for WordPress users, previews as to what’s upcoming in WordPress 3.1, and another killer informative/tutorial post from Justin Tadlock.

Pretty blue links, just after the jump.

In blog posts this week:

• Mojo Themes interviewed their marketplace’s latest featured seller Ruven
• Peter Kim posted a great list of spam-fighting techniques over on the BuddyPress forums. It’s worth a read, particularly if you’re running a community site.
• iPhone.AppStorm has a post up with “essential” WordPress mobile apps, themes, and plugins.
• Stephane Daury, code wrangler at Automattic, posted about the newly-added link management functionality, now added to WordPress trunk. While we’re on the topic, Mark Jaquith updated the WordPress development blog with the new post formats feature that has been added to core.
• On a topic that is pretty interesting to the crew here at WPCandy, theme developer and blogger John Saddington put up a video and lengthy post on when to advertise on a blog.
• Webdesigner Depot has a nice review of five things Twenty Ten’s front-end code does right (though there are easily more than five things right about it!).
• Mashable breaks down the statistics presented in DoNanaza’s market report on the most used content management systems among freelancers. Spoiler alert: WordPress wins.
• Brad Williams, author and organizer of WordCamp Philly, posted his thoughts on the event. Also have a look at the WordCamp Philly blog’s collection of photos and blog posts on the event.
• Ben Gillbanks put up a nice list of troubleshooting tips for those using TimThumb.
• Read James Huff’s (of WBTC) thoughts on the launch of FoodPress.

In tutorials and resources this week:

• Justin Tadlock put together a solid tutorial, as usual, on theme-supported features.
• John Saddington has a nice video tutorial showing how to install WordPress manually on DreamHost.
• ThemesForge has a list of “massive sites” using WordPress. And while we’re talking list of WordPress-using sites, check out Sarah Gooding’s list of 15 non-profit websites running on WordPress at WPMU.org.
• WPBeginner has a tutorial roundup of sorts: one that they claim contains the “most wanted” WordPress tips out there.
• Jeff Starr, co-author of Digging into WordPress, guest posted over at ProBlogger with a list of plugins to “empower visitors”.

That’s it for links this week. If you run across something link worthy, don’t hesitate to let us know about it. If it’s worth a story we’ll jump on it, and if it’s best suited for a community news post it will show up in this space next week.
