Go out on a limb about keeping love's last observations online (6)
I believe the answer is:
weblog
'observations online' is the definition.
I know nothing about this answer so I can't tell whether this works.
'go out on a limb about keeping love's last' is the wordplay.
'out on a limb' becomes 'lbw' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'about' says the letters should be written in reverse.
'keeping' indicates putting letters inside.
'last' suggests the final letters.
The final letter of 'love' is 'e'.
'go'+'lbw'='golbw'
'golbw' backwards is 'wblog'.
'wblog' placed around 'e' is 'WEBLOG'.
Can you help me to learn more?
(Other definitions for weblog that I've seen before include "Internet site for personal opinions" , "Modern record" , "Online record of personal opinions" .)
