在即将到来的"中文网志年会"上，本人被委派主持一个Panel，讨论"Web 2.0 创业与投资"。

我打算邀请五位在2.0 方向创业和投资领域的活跃人士作为研讨嘉宾，目前仍然空缺二个创业人士，希望在这个群组征集一下，有兴趣参加者请不吝介绍自己最近对Web 2.0 创业的一些看法，我会和其他已经参加这个板块研讨的人士共同确认下。

除了希望大家讲解对Web 2.0的不同理解，我可能会问的问题主要集中在近期冒志红提出的这个现象"web 2.0得罪了谁，值得大腕们炮轰？ "。如果你有这方面的观点或者问题，也请不吝发表，以便让这个Panel 更加有趣和有建设性。

comScore在9月11日发布统计分析“Leading User-Generated Content Sites See Exponential Growth in UK Visitors During the Past Year”：2006年7月，英国，主要以免费、用户产生内容（UGC - user generated content）为特征的5个web2.0网站，因流量激增而进入英国网站的前50名。头号UGC网站Wikipedia已列英国访问最多网站的第16位，7月独立访问者达到6,545，较之去年同期增长253%。MySpace列第27位，Piczo列第43位，YouTube列第47位，Bebo列第48位，访问流量都比去年有300%多的增幅。

UGC网站对于用户的粘性，或许比流量暴涨更令人印象深刻。comScore的分析表明，在英国访问最多的50个网站中，上述五大UGC网站，显示出了比non-UGC网站有更高程度的用户参与：使用天数更多（UGC网站每个访问者平均每月使用天数为4.2，non-UGC为3.5天），使用时间更长（UGC网站每个访问者平均使用79.9分钟，non-UGC为33.2分钟），浏览页面更多（UGC网站每个访问者平均浏览217个页面，non-UGC为52个页面）。

部分用户产生内容（UGC - user generated content）网站与非用户产生内容（non UGC）网站的使用时间对比，2006年7月，英国

Average Usage Days per Visitor Average Minutes per Visitor Average Pages per Visitor Average of select UGC sites 4.2 79.9 217    Wikipedia Sites 2.0 10.1 13    MySpace.com 5.4 122.7 333    Piczo.com 4.8 60.9 238    YouTube.com 2.9 60.9 70    Bebo.com 5.6 145.0 428 Average of non-UGC sites among top 50 3.5 33.2 52

其中，Bebo和MySpace粘性最大。2006年7月，Bebo的每个访问者平均访问5.6天、停留145分钟、浏览428个页面；MySpace的每个访问者平均访问5.4天、停留122.7分钟、浏览333个页面。

“Web2.0显然以参与来架构，试图汇聚网络用户的集体智慧”，comScore Europe的常务董事Bob Ivins表示。“通过分析用户参与的统计，很清楚，UGC网站，尤其是社会化网络站点（social networking sites），是广告主和营销者潜在的肥沃土壤。这些网站的用户访问更频繁、停留更长久、浏览更多内容，这意味着营销者有更多的机会沟通关键信息。目前的挑战在于，在保持良好用户体验的同时，找到整合信息沟通的更有效的方式。”

eMarketer以“User-Generated Content Gets Sticky”为题对此做了报道，并指出：由于缺乏non-UGC在英国的具体统计数字，很难了解UGC在英国到底有多主流。但在美国，同样是comScore的统计，却显示一些non-UGC网站，比MySpace有更多的使用量。（这并不矛盾，上述英国的统计，对UGC发布了各个网站的数字，而对non-UGC发布的是平均数字。）

UGC正在流量排行榜上日益爬升，参与正在成为一种生产要素，但不久前国内的互联网大会，却发出了“Web2.0没有商业模式”的集体炮轰，而4个月前“百度还天生是Web2.0”。是失忆，更是悲哀。

Today, the Google Groups team launched a new beta version, available to anyone at groups-beta.google.com. It may have been awhile since you thought of Groups as cool or sexy — if you ever did — but I couldn’t have been more excited to work on the team responsible for making the current Google Groups better. As a designer, I really relished the opportunity to make a Google product that’s been around for years more compelling and easier to use.



One of the things I'm happiest with in the beta version is the new design for individual groups. It’s cleaner and simpler, and yet manages to integrate a lot more features. Group owners can now create a welcome message, upload a group logo and customize your fonts and colors. You can make your group your own, in other words — something you had been telling us you really wanted.



Another thing I'm particularly proud of is the Pages feature, which lets you create web pages inside your group, and work on them with others. Instead of only offering rigid templates, we integrated many of the functions of Google Page Creator right into Groups, so you can create exactly what your group needs: an essay for school, the history your family, a web page with photos, a list of links, and so on.



Some of the other improvements to Groups include:

• Using Gmail's message cards for discussions, which makes them easier to follow
• Adding a Files section so users can share and collaborate on documents
• Helping groups have a better sense of their members with the Member area

Of course, the current non-beta version of Google Groups is still around and you can still use it (although without the cool new features). But we are going to change all of Groups to this new look soon enough — we’re even trying to (gasp!) take it out of beta reasonably quickly. So try out the new version for yourself. And let us know what else we can do to make the experience even better.

Ever since we launched Google Accessible Search in July, one of the most oft-requested features has been the addition of advanced search capabilities similar to those available on the main Google Search page. In response, we've added an advanced search link at http://labs.google.com/accessible in order to refine your searches in various ways. The order of results will continue to take the accessibility of the search results into account.

Here are the types of advanced queries you can perform:

• restrict search to portions of a page, e.g., the title
• restrict search to results in a given language
• restrict searches to web pages found during a given time period
• restrict searches to content in a given file format

And a lot more that won't fit on the margin of this page --- for complete details, see our Advanced Search Tips.
