So what's new in SharePoint 2010 anyway? Microsoft has a library of documentation on this topic, but I thought to pull out the obvious winners. So here is my refined list of new features in SharePoint 2010 that did not exist in 2007. My list will focus on sites, communities, content, search, insights, composites, and office 2010 integration.

Sites:

Line-Of-Business Integration with read/write capabilities.

Enterprise Management Operations offers Web Analytics that provides you with traffic reports, search reports, and inventory reports.

Mobile Connectivity in SharePoint 2010 makes it easy to work on the go with full-fidelity viewing and providing editing capabilities.

A more robust user experience with the aid of the contextual Ribbon and Microsoft Silverlight.

Office Web Applications allow you to view and edit Office documents directly in the browser.

The ability to tag documents creates an extra search dimension thus reinforcing metadata management.

With the help of the Audience Targeting feature, content can be targeted in a site for viewing by one or more specific audiences.

Communities:

The Ask Me About section on a user's profile is a great way for people to not only select their areas of expertise, but also to invite their colleagues to share in their knowledge.

The Note Board is a great way to post comments, ask questions, or otherwise interact with people or site communities.

The Recent Activities feed on a person's profile page is a helpful way to understand what that person has been working on.

With a rich Microsoft Silverlight user interface, the Organization Browswer provides an exceptional browsing experience.

With Social Bookmarks, you can discover new sites from colleagues with similar interests.

Tags, or keywords, help to classify and organize the vast amount of information in your organization.

SharePoint 2010 includes a Tag Cloud web part that helps people navigate through the tag taxonomy by visually depicting the most popular tags.

Tag Profile pages are communities of interest around a specific keyword or topic.

My Network displays a real-time feed of updates from the people you follow and the interest and activities you track.

Enterprise Wikis can help to consolidate company-wide information into a centralized, easy-to-mange repository.

SharePoint 2010 include a 5-star rating system that can be applied to SharePoint pages, lists/libraries, or individual documents.

This automated suggestion service can help to keep your network and interests updated in a seamless, natural way.

Content:

Compliance Everywhere enables content managers to discover and enforce policies on documents, groups of documents, and list items using the same tools they use for non-compliance related content.

Flexible Records Management allowing you to manage records in an archive, or you can manage records in the same document repository as active documents.

Shared Content Types and Managed Metadata Service allowing organizations to share metadata taxonomies and terms across multiple SharePoint webs and site collections.

Content Organizer allows you to automatically route documents to different libraries and folders within those libraries.

Rich Media Management allowing you to store digital assets and share them with users.

Document sets are components, similar to folders, that enable users to collaborate on related documents without having to create a new document library or site. Their purpose is to help organize unmanaged documents and enable collaboration on documents that have all been invested with similar metadata.

Word Automation Services allows you to perform file operations on the server that previously required automating desktop Word, such as converting word documents to PDF.

Accessibility Standards provides built-in support for keyboard navigation and support for industry-wide accessibility standards.

Search:

Refinement Panel and Sorting allow you to very quickly filter the search results by a variety of configurable categories, document types, etc.

The use of user context makes it possible to tune search results by roles, position etc.

Social Behavior Improves Relevance of search results

Thumbnails, Previews, and View in Browser, allowing you to view and page through a PowerPoint presentation within the search results.

Insights:

KPI Details Reports show exactly what data is responsible for the value of the KPI and it includes a description of the KPI.

Enhanced Navigation, including Filtering and Sorting (Top / Bottom 10, Switchable Measures).

Publish Microsoft Excel workbooks to collaborate and share on the SharePoint portal.

JavaScript Object Model is a very cool feature of SharePoint 2010 Foundation Server that enables developers to write applications that access SharePoint data from a .NET application running on a client computer, from a Silverlight application, and from JavaScript running client-side in a SharePoint web part.

Powershell Scripting is a command-line scripting tool that provides an administrator full access to applicable application programming interfaces (APIs), along with the ability to unlock the capability to interact directly with SharePoint 2010 Products to manipulate Web applications, site collections, sites, lists and much more.

Use the Business Connectivity Service to include Additional Data Sources, including External Lists and PowerPivot Workbooks.

Improved Strategy Map Connection and Mapping providing a way for companies to document their primary strategic objectives. It visually shows the goals being pursued by an organization and the relationships between these goals.

The Business Intelligence Center replaces the Report Center that we had in Microsoft Office SharePoint Server 2007.
