To publish your RSS feed you need to segment your data, links and tags and whatnot into a number of individual fields, some of which are required and some of which are optional. The title, link and content are easy, but what about "text input" or "TTL (Time to Live)" or "GUID (Global Unique Identifier)"? If you're flummoxed, this is the go-to place for descriptions of all the settings and fields you need to know.

The "text input" setting allows a data entry box to be displayed within your feed. That data entry box can be filled out by the subscriber, who then pushes a button and drives an action. The action may be to send information back to the publisher, or the publisher may allow the subscriber to do something else, such as enter a keyword and then be driven directly to Google for those search results. "TTL" refers to the number of minutes that the feed is allowed to be cached by a server before the feed needs to be refreshed. And the "GUID" is a string that uniquely identifies an item. When present, a feed reader may choose to use this string to determine if an item is new. [WDFM Annotation]

UrlTrends was developed to allow Webmasters, Search Engine Optimizers, and domain buyers to determine a website's (or a specific page's) rankings in the various search engines and directories. Based on this information you can make competitive analysis of any website with another website -- and from this you could possibly determine whether your SEO tactics are positive or negative to your website; or, if you are a domain buyer, determine if a particular domain should be purchased.

UrlTrends was designed from the beginning to have a different approach to viewing link popularity and other pertinent information. The theory was that webmasters would like to be able to see their link popularity stretched out over time, not just for the current day. This unique approach to viewing the information allows people to make a truly accurate judgment of the website and not be subject to artificial inflation that the instant link popularity reports suffer from.

Currently, the Trend Report allows webmasters to view their linking trends for eight different search engines (Google, Alexa, Yahoo!, MSN, AllTheWeb, Alta Vista, Teoma and IceRocket), as well as the PageRank and Alexa Rank. A recent addition also allows our users to view the number of end-users of a website that bookmarked the website using Furl or Del.icio.us.

Some of us have a great eye for complementary colors and matches--and then some of us still don't understand why brown shoes and black pants are a bad idea. For anyone looking to set an image against a complementary background or find a color scheme, Whats Its Color (their grammar, not mine) is a free web app that can help. Upload an image and the site creates a palette page with a complementary background and a list of unique and dominant colors in your image. Photoshop and GIMP gurus might already know how to sift these kind of things already, but the visible color matching could be a boon for presentation slides or small design projects.

Pipes is a content creation tool (or "mixer") that allows you to aggregate, manipulate, mashup, tag and filter content from around the Web. Content can be from a variety of sources such as RSS feeds, XML feeds, Google Maps, podcasts, Twitter, Flickr and other social sharing sites and so on. Your "pipe", or content, is a unique combination of information that you filter, edit and publish for specific end users -- either for yourself or your subscribers. Think of it as an old-fashioned clipping service that you can use for your own private edification... or you can take the compilation that this tool built for you and republish it on your site. Your blended feed showing snippets from other publisher's feeds does show the source from which it came. Think of it as a byline.

For example, you could filter incoming feeds and posts from all the best search engine marketing blogs and SEM resources using a keyword tag such as "Google AdWords tips" and get every tip from around the Web the second it is published (btw, that's a valuable RSS feed to offer to your subscribers if you are an SEO firm). Or you could create your own brand protection mixer that monitors what the world is saying about your brand, company, product or URL in Google Blogs, Technorati, IceRocket, Blog Pulse, Yahoo News, MSN News and Google News. This is a must-watch trend for Internet marketers. [WDFM Annotation]
