Webware Radar: TravelPost aims to become go-to hotel site

Also: Linkstorm has raised $2.8 million in Series D funding; Zemanta has added support for Last.fm; and Three Melons has raised $600,000.

Travel search site Kayak.com announced Tuesday that it has launched what it calls the "most comprehensive hotel information site on the Web": TravelPost.com. The site provides reviews, content, and rates on more than 140,000 hotels from 200 travel sites. Its content includes descriptions, photos, maps, and reviews from travelers and professionals, as well as integration with Kayak.com's rate search.

Beyond that, TravelPost features Google Maps integration to allow users to search for geographic details about possible vacation spots and its filtering and sorting tools let users narrow their preferences by star rating, property type, brand, and location.

Perhaps most compelling, users will also be able to filter their results based on the reviewer, so they can find similar people to get the most relevant review. Reviewers can be searched for by age, gender, budget, purpose of stay, and which sites they reviewed a hotel on. The site is live now.

Zemanta, a tool that allows users to add relevant content to blog posts and e-mails, announced Tuesday that it has added Last.fm content to its platform. According to the company, bloggers who use the Zemanta tool will be able to add contextual links relevant to Last.fm's tracks, videos, and artist pages. Bloggers using the Zemanta application will start writing about a song, album, or artist, and the tool will instantly pull in the relevant information from Last.fm. (Last.fm is a part of CBS Interactive, which also publishes CNET News.) The new feature is available now.

Online advertising firm Linkstorm announced recently that it has raised $2.8 million from a variety of angel investors. According to the company, it plans to use the funding to expand its sales and improve its platform.

Online casual game provider Three Melons has raised $600,000 in funding from Santander Bank, the company announced Tuesday. According to the firm, it will use the capital to pay for its expenses and invest in growth. No further details of the funding round were disclosed.
