Few small comments:

• adding keywords looks a bit weird, but good enough for now?
• the keyword help text say "select from 30", but I only see 10 or so?
• when I initially add keyword I get a pre-defined list, with things like "big data". If I select these, it works fine, but once I remove it, it's also removed from the pre-defined list.
• when I select or remove a keyword, the counter is not updated until I leave the edit page.
• when the about text is short, its centered on the page:

@jmaassen Here are my answers

• the keyword help text say "select from 30", but I only see 10 or so? It says (max.) top 30 :-). I can add word max but this approach is used for quite some time now and we have not had remarks about it
• when I initially add keyword I get a pre-defined list, with things like "big data". If I select these, it works fine, but once I remove it, it's also removed from the pre-defined list. I cannot reproduce this behavior. Let's have a look at it together
• when I select or remove a keyword, the counter is not updated until I leave the edit page. The counter is indicative and it does not reflect exact count. It is ment to suggest you the keywords that are used often
• when the about text is short, its centered on the page. I think this looks nicer if the text is not wide see example bellow. I can change it if you insist but I think this looks better (see example below)

approved, as Dusan convinced me these are features not bugs ;-)
