I have this really bad habit of buying domains for projects I plan on working on for 1 year only. I recently accidentally lost BeyondTheBrowser.NET and SilverlightCoders.com due to not only moving between US to Australia (i.e. lost track of my inbox) but also due to being extremely busy.

Ok, that's life no problem. I decided to see if could buy back the SilverlightCoders and BeyondTheBrowser domains from the new owners.

SilverlightCoders response:

Am certainly open to selling, is this for corporate use?  A very quick search of equivalent domains at sedo.com has bids ranging up to $5000.  What terms were you thinking of?

Ok, I could go LCA route and pull an Adobe Trademark infringement / protection route, but really it's not worth the hassle or negative PR and in the end it's not that important to me fight that battle.

Yet, after speaking with the current owner, he was more friendly then the most domain squatters I've encountered:

Completely understandable - might also we willing to barter the domain for some Silverlight training.  I'm currently a Flex programmer so you'd be converting me and potentially some collegues/coworkers in the process.  Let me know if that is of interest.

I'll do that for free with or without the domain bartering, so some positive output came out of this.

I then move onto BeyondTheBrowser.NET and see if I can buy back this domain:

Thank you for your enquiry.
A search for "designers block" shows approximately over 119,000 results from Google.
Names such as designersblock.com are very much in demand especially as
there are more than 60 MILLION domain names currently registered.
If you consider that just recently Fish.com sold for $1,020,000,
MyPremierCard.com for $135,250, JMM.com for $55,000 and 
HorseSupplies.com $52,500 etc there have been many other
5 figure sales - I'm sure that our asking price could be considered
an investment for a domain of this quality.
The price of this domain is £7,000 Great British Pounds or US$13,670
(close offers may be considered). 
This is a one off payment for the rights to the domain, however you
will be responsible for paying the yearly registration (approx $30).

If you pay $5000.00 USD for any domain, especially of the above, you're a damn fool. Adjust your wording, re think your project strategy and don't encourage these folks to continue to hijack the Internet for silly potential "profit" margins.

Domain names are over-rated :) and Silverlight.NET vs Silverlight.COM are a prime examples of marketing true power vs random direct URL key entries.

I rate domain squatting for money up there with Viagra spamming.  I must confess, I've had a few offers for Spidaweb.com a domain I own as well as Pvpers.com. I won't sell and I have plans for these post Microsoft, but the numbers have been quite interesting.

Should I ever decide to give them up, I will only do so if there is merit in the new owner having them, like they have an actual plan other than "..I want to create a bidding war.."

Any who, I've adjusted my project ideas, the branding and so on, now to move forward and not pay the extortion money above.
