Thanks to for the starter...
Hashtags, the practice of tagging posts with a keyword preceded by #, became popular via Twitter.
Hashtags are a solution to a problem. The problem is that Twitter search sucks.
The hashtag solution, however, comes with its own problem. Some or most of the tweets on Twitter that fall under the hashtag's topic do not get hashtagged by the poster. As a result, searching a hashtag brings up only a subset of the results you're looking for.
Worse, people who use hashtags tend to be the self-promoters. So hashtag searching favors people actively seeking attention, and is blind to tweets by people who are just posting great content. I think I used to post pretty good stuff on Twitter. In my more than 14,000 tweets, I don't think I ever used hashtags.
Google+ doesn't need hashtags, because it has three things Twitter does not have:
1. Great search. Looking for something? Search for it! Unlike on Twitter, or Facebook, for that matter, you will find it.
2. Longer posts. One reason Tweeps feel the need for hashtags is that the 140 character limit greatly reduces searchable words in each post. Without the restriction, people are likely to use a word or string of words you can use to search and find the items you're looking for.
3. Comment threads. If search fails you, just post an item telling your circle friends what you're looking for, and they'll help you find it.
Hashtags are a crutch for a crippled service. Google+ doesn't need the crutch because it's not crippled.

Previous to that I was VP, Developer Community at Bungee Labs after spending 5 years at Microsoft Corp in various positions (my last role there was as Community Program Manager for the Data Programmability team, Microsoft Corp, Redmond, WA...more on this at my old blog here). I moved to Redmond, WA in 2005 from Microsoft UK as International Program Manager for MSDN and TechNet for a year driving the globalization strategy for these two networks. In 2002 I joined Microsoft UK as Online Customer Experience Manager (in CRM and Online Marketing Team) and did that for a couple of years.
In 1996 I joined Bluewave, a London-based startup, and remained there for 7 years (an online marketing, web design and development agency) as Sales and Marketing Director and then COO. We succesfully completed the sale of Bluewave to Maersk Data (now part of IBM) and shortly after that I took the leap to Microsoft.
