Automattic.com just released a collection of plugins as one super-plugin called Jetpack. As they explained it, the goal was to bring eight of the most requested features available on WordPress.com to the millions of self-hosted WordPress sites in one easy-to-install curated package. Lets take a look at each feature:
Stats
This feature is the same stats-tracking module that all WordPress.com blogs use. It loads a small smiley-face image on each post and page view and uses that to track page views by visitors (Googlebot and other non-Javascript-enabled visitors wont be counted). On the Stats page in your wp-admin, it will give you basic information on the number of visits, the search terms/referrers that brought them to your site, the top pages or posts, and so on. It doesn’t give you any more detailed information, such as the browsers and browser versions of each visitor, the total number of unique visitors, the countries they are from, etc. For those kinds of statistics, youd need to use a more advanced statistics service such as Google Analytics or GoSquared.
Twitter Widget
This is a widget that will show a list of the latest Tweets from any Twitter account. The configuration is easy; simply drag the widget to any widgetized area in your theme, pop in your Twitter username (or someone else’s), configure a couple of other options if you want, and boom, there you go! Instant Tweets!
Gravatar Hovercards
This is one that’s easier to explain with an image than without. If the commentor has a Gravatar profile the information they have included will appear when someone hovers over their avatar image in the comments. You can see a live example on the WordPress.com Gravatar Blog where they first revealed the new feature. With Jetpack, you can easily turn this feature on or off.
WP.me shortlinks
If you click on the Get Shortlink button when you are on the post edit page in your wp-admin, normally it would give you something like http://mydomain.com/?p=34. This often isnt that much shorter than the original permalink, so it isnt that useful for posting a link to Twitter, for example. With Jetpack, you will instead get a WP.me link, such as http://WP.me/j7gv9, which is obviously much shorter. Of course, you could also use bit.ly or even roll your own link shortener solution, but this one is effortlessly integrated into the post editor screen.
Sharedaddy
This feature lets you easily add those ubiquitous sharing buttons you find on most websites, including buttons to Tweet, Share and Like on Facebook, Digg, send by email, etc. The configuration is relatively simple, but the buttons themselves might require some CSS attention if you really want them to stand out (or not stand out as much).
LaTeX
This is something that likely wont be used by many, but will be highly appreciated by those who need it. LaTeX is a markup language for writing mathematical equations, formulas, etc., and this part of the Jetpack lets you easily include them in your posts.
After the Deadline
This plugin lets you check your spelling, grammar, punctuation and style from the post editor. It is more powerful than the regular spellcheck integrated in Firefox. It can check for misused words (example: accept and except, or their and there). It will warn you when using clichés or jargon. It is not a replacement for careful reading and editing of your writing, but as is the case with Microsoft Word or other word processors, it is a useful tool to help you minimize and correct common errors.
Shortcode Embeds
Shortcodes are small macro codes enclosed in square brackets that allow you to access some special functionality from within a page or a post. Jetpack comes with several media-related shortcodes that make it easy to embed a video from YouTube or a presentation from Slideshare into your post. Each one has its own parameters that may or may not be required, so youre better off reading the instructions for each one.
The shortcodes are:
archives, audio, blip.tv, dailymotion, digg, flickr, googlevideo, scribd, slide, slideshare, soundcloud, vimeo, youtube, and polldaddy.
Future?
The Jetpack site as well as the plugins options page in the wp-admin include teaser boxes that hint at upcoming additions to the package. I wont speculate on what they might be, but please go ahead and do so in the comments below!
Soar or fall?
For the power-user or site developer, Jetpack is probably not the ideal solution. Each front-end feature adds extra weight to your site (in javascript and extra http requests), and there may be other plugins or even custom code that can do the same things but with more options or leaner code. For the casual blogger however, it adds some (mostly) useful features and even exposes some that they may not have even been aware of (Hovercards, anyone?). I probably won’t use it on my own sites, but I’m looking forward to seeing what other functions will be included in the future.
