一直没有留意到flickr的这项功能：彼此建立联系contact的用户可以互贴标签tag。这给flickr衍生项目带来了更多的可能性。不过目前的现状是国内用户的标签使用率远低于国外用户。

另外，5月份flickr由beta版升级为gamma版，个人感觉旧版更好用，例如batch tagging在新版躲藏在多层菜单下，而且界面更为繁复。

话说一呼百应的flickr兴趣组当属what's in your bag了。2628个成员的人气和1802张照片的内容一举满足当今社会人们暴露和窥伺的双重需要。当然网络的匿名性使之蔚然成风。试想有谁愿意当街给你翻看他/她包包里的所有家当？所以，当有人振臂疾呼what's REALLY in your bag时，只得人气121，照片71。

极少可能去看的Ladies' Home Journal刊登了一篇好文。

Skip a Stone A master shares his secrets.    For years Jerdone Coleman-McGhee has held the Guinness world stone-skipping record, and in 1994 winged an eye-popping 38 skips in one toss. How does he do it? McGhee, also the author of The Secrets of Stone Skipping (Stone Age Sports Publications, 1996), shares four key steps: 1. Pick the right stone: It should be of uniform thickness -- or thinness -- and about the size of your palm. And it should weigh about as much as a tennis ball or whatever you can comfortably throw. Too heavy and your load won't launch aerodynamically; too light and it'll be like heaving a sponge. 2. Hold the stone between your thumb and middle finger, with your thumb on top, and your index finger hooked along the edge. 3. Stand facing the water at a slight angle. Try to keep this form throughout. Your wrist should be fully cocked for a forehand pitch when you release the stone; the lower your hand is at the release, the better. 4. Throw out and down at the same time. The stone should hit the water as parallel to the surface as possible. Try throwing as fast as you can -- quickness is the key. Release the stone with a sharp wrist snap to give it some spin, then watch it skip. CBS刊登了日本人的研究成果： TOKYO - Whiling away a summer afternoon at the cottage has taken on a technical edge thanks to researchers at Tohoku University in Japan. They have perfected a simulation of the magic angle for skipping stones across a lake. Throwers should tilt stones about 20 degrees to the lake's surface, an angle first predicted by French researchers last year. Shin-ichiro Nagahiro and Yoshinori Hayakawa of the Tohoku University Department of Physics in Sendai, Japan, created a mathematical formula to confirm the French experiment. The Japanese researchers used a numerical method called smoothed particle hydrodynamics to simulate the skipping stone. They also derived an equation describing the disk's motion. Both methods provided a confirmation of the magic angle of about 20 degrees. Their work was published on Tuesday in the journal of the American Physical Society.

接到lawrence的blog tag游戏的邀请，于是在去长白山的颠簸路上检讨自己旅行时的怪癖。

（一）总是掐着时间在最后一分钟冲到check in柜台办理登机手续。得意自己每次在不同难度的情况下都因计划精确而得逞。但今天一早大雨，打不到的，然后堵车。路上果断放弃常规路线和后备一号路线，采用极其冷门的后备二号路线，并调用先抵达机场同事的力量，终于在晚到10分钟的情况下顺利拿到登机牌。

（二）总是在旅行前打包时煞费脑筋。会将各物品按分类包裹，包裹方式和物品组合关系到我那只小背囊能否装下方方面面。常常花老半天翻箱倒柜就为寻找一只用于包裹某类物品合适大小的塑料袋！

（三）不论冬夏，每天必须洗澡洗头。如果在外旅行没有条件洗澡，头则一定得洗。去年游完北欧回国，先是连夜坐长途大巴从斯德哥尔摩回奥斯陆，然后早上从奥斯陆飞阿姆斯特丹，在阿姆斯特丹Schipol机场，已是污糟邋遢，想着还要再熬12个小时的飞机，头愈发奇痒难忍。于是当即拿了包Rejoice sachet在洗手间在众多各国各异的目光下把头给洗了，还用洗面奶舒舒服服地把脸也洗了个白白，登时精神了很多。后来在飞机上挤在众人之中也神情坦然，并暗自庆幸自己的先见之明。

（四）上飞机坐下后的第一件事是把鞋脱了，让脚好好透透气。即使穿着拖鞋，也会把拖鞋脱掉。

（五）认为使用各著名景点的座厕是加深与该景点设计和管理交流的绝佳机会。当然首先是解决了内急。难忘的座厕top3：瑞士St. Gallen大学管理学院宽敞又私密，极具现代感的toilet；维也纳Museums Quartier的toilet；慕尼黑皇宫里超高层高，极为古老的toilet，给皇帝设计厕所也很有讲究啊。
