if you already know songs on guitar or similar it's surely a fairly easy matter to transfer them to a "uke" once you find your way around the instrument.

Very true, but I was pitching at uke players. In fact I mostly find chords from guitar sites which is fine for a lot of songs, but for folk songs I often find it best to work them out myself. I find guitarists often go over the top and add a lot of unnecessary chords and use "extended" chords - just because they can I often suspect.

Of course, many songs wouldn't necessarily suit the instrument and you have to arrange the material in a "uke" way...

That's true for any instrument. In fact there are songs which best sung unaccompanied and are spoilt by adding any sort of accompaniment.

you can't really use finger picking styles associated with guitar or other techniques which might be associated with the banjo or mandolin etc.

Not true. I have heard very effective finger picked accompaniments on the uke. It is true that you don't do it in the same way as on a guitar as there is no real bass and the re-entrant tuning gives a different flavour but it can be and is done. I prefer to use a strummed accompaniment myself but I am full of admiration for the creative approaches to the ukulele you see on You Tube and in the ukulele forums.

Also there are a lot of people who have adapted clawhammer banjo style to the uke and it works well. Search on You Tube for "clawhammer ukulele". You might just be surprised.

As to the blog: Overall I did feel it was worth at least giving it a go. It may not be useful to you but if it's useful to someone, then it's worth doing. I had a pretty positive response on the ukulele forum.
