Well, unfortunately I've got the same e-mail but the things to be even more sad, those "a cuple of weeks" is next week, precisely on 24th May. They started 4 years ago and I've seen the glory of it and the (unfortunately) inevitable ending. I tried to use it for quite a while and I've got as many of you followed as I could find but even at the beginning there were not many of those on "higher positions" of SSiW who would "clec" much. Many posted only some clecs and went away so our mini SSiW network became more and more quiet until I went quiet too.
I agree with @robbruce about that learners might be more eager to post there than those of us who use Welsh on a daily basis one way or another.
"You using Welsh on a daily basis!?" you'd say ... Yes in a way I do so if not the other way than to a bit teasing and "torturing" my co-workers greeting them in Welsh and asking them how they are ... They can't speak but understand what I'm asking though.
And yes, there's something to learn from "failure" for sure. I was actually a bit sad that I couldn't find some businesses like BBC Radio Cymru and them alike or if they are there they posted just one and only clec (like S4C for example). Such brnads should be the leaders in making one network in solely one language alive but except for some first weeks there was not quite real interest in being present there.
So, tomorrow one week on the Clecs will be no more ...
Hwyl fawr @Clecs a diolch am y popeth.
And for all interested, here on their Facebook page is their whole statement - unfortunately for those who didn't learn enough to understand yet - in Welsh.
