So after using G+ for few days, what are the features you like , what do you miss and what do you hate As per me

– the best feature is ever present notification button and share box on google properties
– unlimited photo storage for picasa or shall we say google photos
– of course selective sharing via circles or just email
– android app ( though it seems sparse at times)

hate or miss
– Sparks – my friend I had high hopes from you, seems like a half baked product
– Limited folks – that is expected, hopefully more people will adopt it
– how to embed google docs in it
