The number of people who either participate on the Board, or lurk, is small in relation to all sellers. 

Therefore, a call to boycott the site (as has been asked many times over the years) would be ineffective. 

As a buyer, the number of items in the areas I look at, and buy in, are very noticeably reduced. 

I can only assume that all these changes, over such a short period of time, is having some sort of effect. 

That effect, I assume, will be on eBay's bottom line  -  perhaps not too much of a dent, but enough. 

I still buy - if the end price is right - but everyone must seek out the alternatives which suit them. 

But you must ask yourself,  what other sites give you the opportunity to sell to such as wide an audience as this does. 

Depends on what you sell  -  but DYOR before making a mistake.
