please answer question 1-7 one by one in detail

Stormhoek Winery a small winery in South Africa (stormhoek.com). Annual sales in 2005 were only $3 million, but with Web 2.0 technologies sales grew to $10 million in 2007 and are projected to reach $30 million in 2010. The company devised a marketing campaign called "100 Geek Dinners in 100 Days." One volunteer would host each dinner, which would be used as a Stormhoek wine tasting for several dozen guests in the United Kingdom and the United States. How can you get 100 people to host a wine tasting and how do you find 40 to 60 guests for each event? The answer: Web 2.0 technologies. Here is what the company did. Blogging. The CEO of Orbital Wines, Stormhoek's parent company, in collaboration with a well-known blogger, Hugh Macleod, wrote dozens of blog entries about the events, soliciting volunteer hosts, including bloggers and wine enthusiasts. Wiki. Each volunteer was provided with contact and location information on a wiki. The wiki technology was mainly used for customer relationship management (CRM). The wiki included wine-related cartoons and other entertainment and advertising. Podcasts. Web-content feed (enabled by an RSS) was used to push information to participants' inboxes. Information included wine news, wine analyses, and descriptions of the 100 parties. Video Links. The corporate blog supported video links. Bloggers could cut and paste embedded links to YouTube videos directly into an entry. Shopping. The blog site acted as a portal to Stormhoek and included support for order placement and shopping carts for promotional "swag," such as posters and T-shirts. Mashups. An interactive map was integrated into the wiki using mashup software. This allowed dinner hosts to display a map of the location of the event. Also, guests could click an event on the map to make a reservation, get a reservation confirmation, send a query to the host, and receive photos of the house and the hosts. The company's wiki also had a link to the host-blogger's homepage. The home parties were attended by over 4,500 people. and the publicity enabled Stormhoek to triple its sales in 2 years (mainly in the United Kingdom). The only problem was a profusion of blog spam-random comments that were automatically posted by marketers for promotions. This required a daily purging and cleaning of the blog from unwanted postings. The blogging resulted in word-of-mouth (viral) marketing publicity. The blogging was done by a profes- sional blogger (Hugh Macleod at gapingvoid.com). The blog offered a free bottle of wine to any blogger who was of legal age and had blogged for 3 months. Macleod also organized the 100 dinners described earlier. Technorati like RSS pioneer Dave Winer have attended some of the dinners. A final word: Stormhoek wine is really good! Viral marketing cannot sell bad wine. Connection to Social Networks. In January 2011, Stormhoek was connected to social networks in the following ways: A dedicated group at Facebook A video channel at YouTube A photo and video collection at Flicker (Stormhoek's photo stream) RSS feed service Was followed on Twitter Sources: Compiled from Bennett (2007).
