I can imagine it must always be hard to market a piece of software when it does a similar job as another, free, utility. I personally have been using URLWell for many months and find it unobtrusive and very finctional. LinkMenu, on the other hand, has quirks that made me delete it after only a few minutes and could not recommend it.
Moreover, I don't paricularly appreciate it when developers tell me "Note : this is the last version I will release unless I start getting purchases". Well, tough, being coercive in this way is definitely counterproductive, sorry.
