ReadWriteWeb

China enjoyed center stage this week thanks to President Obama's visit. Naturally, trade relations were on the agenda.

For Internet companies sitting in the US, news reports that chronicled the President's every move in China were a visible reminder of the business opportunity that may seem a click away.

A few weeks ago, I spoke to someone who had finally reached the end of her rope with an obdurate boss. Having suggested a series of social media initiatives, only to see them wither on the vine as he refused to either push them forward or cancel them, she was ready to move on - not just to another job, but a whole different organization. (Possibly the mob. She has recently dreamed up some innovations on the homicide front that she's eager to try.)

Our mission at ReadWriteWeb is to explore the latest Web technology products and trends. We're fortunate to have a great group of sponsors who support this goal. So, once a week, we write a post about them; about who they are, what they do, and what they've been up to lately. Pay them a visit and show your appreciation of their sponsorship of this site. Pay them a visit or tweet them a "Thank you" (see link below each sponsor) to show your appreciation for their sponsorship of this site. Or you can follow all of our sponsors at once using our Twitter list.

Interested in being a ReadWriteWeb sponsor? ReadWriteWeb is one of the most popular blogs in the world and is read by a sophisticated audience of thought leaders and decision-makers. We have several innovative new features in our sponsor packages that we'd love to tell you about. Email our COO Bernard Lunn for all the details.

Here is this week's ReadWriteWeb events guide. As always, you can download the entire event calendar in iCal format or import it into your Google Calendar. You can also import individual events using the link beside each entry. This events guide is a weekly feature here on ReadWriteWeb. We publish it every weekend, as good a time as any to review your conference plans.

In this edition of the Weekly Wrapup - our newsletter summarizing the top stories of the week - we report on President Obama's (non)-use of Twitter, take a look at the past decade in the media industry, review the latest statistics about blogging, question if Oxford Dictionary should've chosen "unfriend" as its word of the year, and more. We also check in on our two main channels: ReadWriteEnterprise (devoted to 'enterprise 2.0' trends and products) and ReadWriteStart (dedicated to profiling startups and entrepreneurs).

Once the service for those serious enough to pay for the privilege to post, TypePad recently released a free "Micro" service. The company made the decision to offer a free product realizing the demand for a platform more formal than Twitter and less formal than Wordpress or Typepad's original product. ReadWriteWeb compared TypePad's Micro against 2 other leading light blogging tools. Below are our thoughts:

Roambi announced a pro version of its iPhone application this week that syncs with Salesforce.com and other cloud-based services or on-premsie sales environments. It's a visualization application, providing mobile workers with a pretty cool way to see sales information.

Integration is by far one of the most significant trends we are seeing in the enterprise space. It's a wave, really, marked this week by Salesforce.com and its move to turn the Force.com development platform into a service that makes all of its applications social.

It appears that the time for freemium music services in the US has passed. Earlier this week streaming music site Imeem sold to MySpace for under $10 million dollars while laying off a large number of staff. For a company with all four major record labels signed, more than 15 million uniques a month and well over 5 million tracks in its catalogue, it came as a sobering blow to the industry. While many companies move to a subscription model, 8tracks continues to forge along in what some describe as a convenient loophole. As of this weekend the company is publicly launching its API for Boston's Music Hack Day.

The Web constantly changes and evolves. That, of course, is what makes the Internet so exciting, but it also means that finding older versions of a website is hard. The current push towards the real-time web is making this problem even more apparent. Memento, a project based at Old Dominion University, wants to make it easier to access older versions of a web page without having to go to the Internet Archive. To do this, the project is using a relatively obscure feature of the hypertext transfer protocol (HTTP).

The semantic Web has long been heralded as the future of the Web. Proponents have said that Web experiences will some day become more meaningful and relevant based on the AI-esque computational power of natural-language processing (NLP) and structured data that is understandable by machines for interpretation.

However, with the rise of the social Web, we see that what truly makes our online experiences meaningful is not necessarily the Web's ability to approximate human language or to return search results with syntactical exactness. The value of the semantic Web will take time because the intelligent personal agents that are able to process this structured data still have a long way to go before becoming fully actualized.
